Yes, the true thing here is to mesure if the effort involved is
outweighted by the benefit optained.
The problem here is not so much the ocaml suite itself, but the load of
libraries that need to be rebuild for each release independently.
And it has all to be in a way that is friendly to the autobuilders.
That said, it can be done, quite easily on top of that, but i didn't had
time for this right now, and other stuff were more important.
Friendly,
