In which sense would it be wrong?
I can see an argument that such a `-I` would tend to be redundant on
systems where Emacs was "installed properly", but even on those systems
I fail to see what would be "wrong" about it.

IME it's what most users expect when they install (via `package.el`)
packages that come with a module, and it's also what most of the
developers of those packages want to offer to their users.
I have no intention to impose such an approach as the only supported way
to install a module, but I don't see what's debatable about providing
good support for packages to be able to compile their own modules.
