Why don't we just turn off MOZ_BLOCK_PROFILE_DOWNGRADE?

I see this exacly the same. I never found any problem while downgrading Thunderbird. The first real issue after downgrading I ever
had was MOZ_BLOCK_PROFILE_DOWNGRADE. For a test I downgraded from TB 68 to 60 and even to 45.8, but could't see anything broken.
For beta testing and regression finding you often have to downgrade, which is now very frustrating. And it also happens very often
that a normal user is downgrading. I'm in a Mac user forum and a lot of support questions there are regarding downgrading to an older version
of any given software (because of dislike the new UI, missing features in the new version or whataver reason). For my oppinionen
MOZ_BLOCK_PROFILE_DOWNGRADE will give a lot of support questions an a lot of angry users. At least we should give the users a possibility
to switch MOZ_BLOCK_PROFILE_DOWNGRADE off by there own risk and defenitely warn the user before launching the new version, that he
would not be able to downgrade afterwards.
