My impression is that all 4.07 packages apart from ocaml@4.07 itself are
libraries; "guix refresh -l ocaml@4.07" returns only packages of the form
ocaml4.07-xxx. So by recursively removing leaf libraries, nothing will
be left over except for the bootstrap.

Unison has a newer release 2.53, with the following NEWS:
* OCaml >= 4.08 is required to build unison.
* unison can be built with (unreleased) OCaml 5.
So this could be tackled (after the core-updates merge, I would say).

Then there is usync depending on unison. It is unmaintained with the last
commit 5 years ago, so can maybe be dropped. Well, it is a simple scsh
script, so will probably continue to work by calling the unison and rsync
binaries.
