I don't claim to understand debian policy but I think that freeIPA
should, just as sssd should, expect to need to rebuild after any Samba
version upgrade.  (And therefore Samba backports may not be possible,
and this may be why Samba is often installed in a custom prefix by 3rd
party packagers). 

I changed the libndr.so version upstream in Samba 4.15 to properly
address regressions from earlier fixes in that library.  Almost all
users of the library will have been impacted by the changed function
signatures, no fallbacks are/were possible. 

Upstream Samba doesn't have the resources to provide a stable ABI to
libndr, but the output of PIDL (eg compile-time API) should still
work.
