I hate the import option as well, since many users blindly use it. Like David Maudlin, I've also migrated my work environment forward from version to version, though.
When I first work with a new version, I use the standard work environment for initial testing / learning (or at least review) of all new features. Then, I import my prior version WE and customize it based on how I've seen GS manage the new features.
Something that was very frustrating about this migration in some prior versions - I think it was 11? - is that the "new commands" that are supposed to be listed in blue, so that you KNOW they are new and might consider adding them to your WE - included the new commands of the prior version as well. Made it painful to wade through.
Thankfully, in 12, the 'All new commands in alphabetical order' indeed lists only commands new to 12, making it much easier to update WE from 11. (Those skipping a version will have more of a challenge.) I usually go through the list of new commands, All commands by theme (to find where each blue/new command fits according to GS), and sometimes the standard menu scheme, again to see GS's intent to see if I agree or not.
Generally, I put things where GS recommends, so that it matches the help file/etc, but the 3DS Import, just makes no sense in the Design > Design Extras menu and I put it in the File > Libraries and Objects menu.
