Please be cautious when removing or changing deprecated tags, such as 'cycleway=opposite'. Replace them with 'oneway:bicycle=no' if the street is still bikeable in both directions.
Here is the description for this tag oneway:bicycle=*

In the case of Herschelstraße, you are correct for tagging that there are no bike lanes, but please do not remove the possibility for bikes to drive in both directions.

I saw that change from you a few times and corrected it. Please be careful when removing or changing that tag.
