making cabal-install into a library?

If you're using a subprocess, then you're always using the same, the installed
cabal-install version.

With a cabal-install library, your application might use an other
version of cabal-install than the installed cabal-install binary and
this might result into issues.

Also if it seems counterintuitive, the best solution might be to have
a library that usese a subprocess ;).
