For the same reason, I wrote the install.el elisp package which can take
a single .el file or a tarball of an elisp package and install it.

It is a completely different solution to your problem, but I think that
your code addresses just the issues that are left in install.el.

It's still very simple (or rather: simplistic) and needs more work, but it
might be interesting to integrate it with your code.

I have attached my latest install.el.
