Why not make this opt-in instead and have it `enable-archiving`?

Because as it currently stands this patch doesn't account for:
- people who dont have channels but run guix lint
- people who may not read the manual and have their code sent to SWH even tho they didnt intent it

Guix should strive to do what it is explicitly asked. nothing more. which is lint in this case, not archiving.
