The unison in Debian 10 is compiled with OCaml 4.05.0, which is long
gone. The only way to synchronize with a buster machine is to use unison
from buster.

I'm sorry I haven't been sufficiently clear on that.

Since the version of OCaml changes at each Debian release, there will
not be /in the archive/ a package (or metapackage) that will be
compatible with two successive Debian releases (or with stable and
testing/unstable). My goal with the new packaging structure is that once
a version of Unison is installed, it may be kept installed even after an
upgrade of Unison (meta)packages. So, for example, if we transition to a
new version of OCaml (say 4.11.0), I will ask for the removal of
unison-2.48 from the archive and upload a new unison-2.48+4.11.0. In
this hypothetic future, unison-2.48 can be kept installed on systems (or
installed from snapshots) where its compatibility set is needed.
Moreover, unison-2.48 and unison-2.48+4.11.0 would be co-installable,
easing migration from one version to the other.


Cheers,
