Remapping is boring, and takes away time from doing real mapping.
However, with 1st April date to expunge non licence compatible data from the map, it is not too soon to start remapping.
In Australia, only about half the map is compatible with the new licence conditions. About a quarter is the IP of 44 licence rejectors, and the remaining quarter is made up of about 1,500 non-acceptors, who are signing up at the cracking pace of around .22% per week. It's clear I can't wait for the non-acceptors to sign back in.
I've made a start on my local area, and I've quickly learnt that it's quicker to just replace stuff colour-coded as affected than to work out if the changes made by rejectors/non-acceptors are critical or not by perusing the history.
At least doing local changes, I know what the streets are called, where the bus stops are, etc, and can do it all from desktop mapping. To remap the entirety of Australia by 1st April is, I think, an impossibility.
