frozen versions?

[c-cube]

Hi,

I like setup-ocaml and I use it in many projects. However, it tends to break when the underlying systems are updated (currently #529, previously in my case #361, #264, #479). I would love a way to specify a fixed version that uses a fixed underlying OS, even if it means I have to upgrade the version from time to time (e.g. ocaml/setup-ocaml@v2.16, update to @v2.17 if the OS dependencies get too old).

Is that even a remote possibility, or structurally impossible?

In fact, it's possible to have fairly strict version control of the action by specifying tags. For example: ocaml/setup-ocaml@v2.0.3, ocaml/setup-ocaml@v2.0.4.
