Comment (by Joel Shapiro):
Replying to [comment:2 Mariusz Felisiak]:
> Thanks for this ticket, however, I'm against this change. First of all
it is backward incompatible. Constraints have been introduced in Django
2.2 and constraints with a name of length greater than 63 characters are
valid on other databases (64 on MySQL, 128 on MSSQL, etc.). I agree that
it is a inconsistency between constraints and indexes policy but still we
need to be careful with introducing incompatibilities. See also a related
ticket, #30614.

Thanks for the fast response!
Yes, I agree. Not great to break compatibility.
