So why do you want to obfuscate glabel with it? For people to start
depend on it? Once we start supporting 4kB sectors what do we do with
such a change? Remove it and decrease version number? What people will
do with providers already labeled this way?

If its temporary, just allow to list providers you want to increase
sector size in /boot/loader.conf. Once we start supporting it properly
people might simply remove it from loader.conf and it should just work.

Glabel is not for that and I don't agree for such obfuscation.
