The shared object file has to be at the right place as well.

This assumes that we have dependencies between extensions, which we don't
have anyways. Now if extensions depend on each other the order is
important. I assume that the loading order is also the order that the MINIT
is called, which then would also put dependent php files in order.

Yes maybe, although I don't see the benefit for userland TBH, compared to
extensions. Extensions are about declaring functions/classes, prepend is
normally about actually "executing"/running code.
