Samba releases are supported for 18 months after the release.

Debian's schedule is here:

Assuming other things stay equal it looks like Samba 4.12 would EOL in
2021-09 and debian will EOL in 2022 sometime.

Sure.  That's why we ask these things.  

Additionally, you will always have the ability to install a backported
python3, or build just the fileserver (eg --disable-python) with
something as old as Python 2.6.

I hope this helps clarify this proposal.
