It is. It is exactly related to the fact that thunderbird is supported,
and that extension are not despites depending on it.

That precisely because we tell "security and bugfixes occurs only on
main" that contribs got broken, since the security team do not care to
not break contribs packages.

So basically, you want a --nodeps ? 
If there is a requires, there is usually a good reason. Engineering is
not randomly adding line to a file until it work.

No. If there is stricter dependency, it is precisely because there is no
guarantee of any kind of ABI between thunderbird versions. The same goes
for firefox.

No. Not at all. 
The problem is linked to the difference of support between main and
contribs.
