I don't agree with this style. Is it merely because of the shape? For a simple straight central island, you would keep it the same. Think about a two-way road intersecting a one-way road. This isn't done for roundabouts either.
Or why not make the `*_link` all the way through the next junction? -

This is mainly an inconsistency that I found when I look at somewhere nearby, at Fung Mo Street: https://www.openstreetmap.org/#map=19/22.34199/114.18973
Using eg Google Maps to look at the street markings, one can see that Fung Mo Street has the yellow "slow down" markings and marked as "trunk_link", but right at this changeset, it also has the "slow down" markings but was marked as "tertiary". This seemed strange.

But still, regardless of whether it should be "trunk", I think at least it should be a link of some sort. I hope I did not get anything wrong.

It is not without controversy. You can read the aftermath of some strong words. https://wiki.openstreetmap.org/wiki/Talk:Highway_link#Y_Junctions_should_NOT_be_classified_as_links
Fung Mo St has a u-turn. Then `=*_link` shows it diverges into 2. But Ching Tak St doesn't.
Would you do the same if it connects to Lung Cheung Rd at 90 degrees? What is the reason for the difference? Determining purely based on whether it curves is not consistent and useful.
Another comparison can be made at roundabouts. You won't change the eastern end of Fung Tak Rd to `=secondary_link` simply because it splits at the end, would you?
This can be compared with divided roads. Hypothetically if Shatin Pass Rd is only channelized by an island near the Fung Tak Rd junction, suddenly it has to be considered as a `=secondary_link` , despite having no other significant difference with reality. -

It's not about the physical design, or whether it is an "exit" or "entrance" . Contrary to Google Maps, which has many other arguably bad designs.

Hmmm, upon review from Google Street View, by looking at the street name plates/markings, it seems the curved section is actually not part of Ching Tak Street, and therefore can be marked as trunk links belonging to Lung Cheung Road, bypassing the entire Y-junction fiasco.
As long as we can agree "the curved section is not Ching Tak Street", then it follows that the specific segments should be marked as trunk links. I'm not gonna decide anything on the general case.
If everything is OK, then I'm gonna make another edit a few days later to adjust the relevant street names.

No, don't say you are copying from Google. This is not allowed. It's a copyright infringement.
I don't agree. Street names don't decide anything. In fact, `*_link=` is described to not have names internationally, which is not applicable. In Hong Kong, the street naming have a very specific organization that defies routing expectation. For example, on slip roads, the name of the main line applies until the gore. Then routing will be confused unless it evaluates the name afterwards. -
Comment from Kovoschiz
Street naming is inconsistent. See Fung Mo Street.
It can also be incomplete. Many road sections don't have a street name gazetted or signposted.
The incompleteness and inconsistency can play together when addressing doesn't follow the absence of street naming.
Another clear example is how `=roundabout` is described to not have names internationally unless it is the junction name itself. But HK applies the road name to all roundabouts. -

Eg Ma Chai Hang Rd rounabout's street naming is Ma Chai Hang Rd.

I really did not expect to uncover this many topics from this seemingly small edit. It seems there are way more inconsistencies than I expected at the first place.
I'll just hold this for a few days and then revert the tertiary->link change.
