This should be integrated in the backports.d.o repositories.

Should the description from backports.d.o be adjusted then? For now, it reads:
Backports are packages taken from the next Debian release (called "testing"),
adjusted and recompiled for usage on Debian stable.
Alternatively, can you please explain how this case doesn't fit?
We didn't need to backport Unison in the past because it used to work well
even with different OCaml versions. Now, this changed in 2.48 and we are not
able to offer sync between Stable and Testing machines anymore. In fact, the
"issue" was triggered by the fact that some internal structures changed in
some OCaml modules rendering Unison <2.48 unusable with recent OCaml version.
This is now fixed in Unison 2.48... hence the backport of Unison 2.48. But
there is nothing to fix in Stable...
My only doubt right now (about the backport) is about #805456. It would
be great to hear about the submitter before exposing Unison 2.48 to users
of stable.
