You're right that we should think about those users, and try to minimize 
the number of users who will run into that situation, but it seems 
difficult to completely avoid it.

Enigmail could open a tab (each time Thunderbird gets started) with a 
warning that says "reminder, please continue to use Thunderbird 68.x 
until August-25 because ...".

Or we could try to add a check to Thunderbird 78 that is executed very 
early during the startup code (before any profile migration code runs), 
which checks if the Enigmail Add-on is present in the profile. If it is, 
show a warning "You have the Enigmail Add-on installed, which is no 
longer supported by this version of Thunderbird. Integrated OpenPGP 
support is under active development, and expected to be ready by 
August-25. Please continue to use TB 68 until August-25. Thunderbird 
will now quit."

Delaying the stable 78.x release until OpenPGP is sufficiently complete 
would be an easier and more reliable approach (e.g. declare 78.0 and 
78.1 as beta versions), but in my understanding this isn't an option.
