Question about global solve for projects with OCaml 4 & 5

[mbarbin]

In the doc page in the overview section it says:

A key point is that OCaml-CI will run an opam solve for all of the dependencies in all the*.opam files together.

So, if you depend on OCaml 5 in bondi-lwt.opam, then a build will only happen on that version of OCaml, even if the other two packages could run on earlier versions of OCaml.

Pragmatically, it looks like this isn't true anymore (I'm guessing probably an artifact of an earlier version?) as witnessed by the partial build using OCaml 4 of a subset of the packages of the vcs project under my username.
