Package.el did not attempt to avoid those problems until:
commit 67c6906a5f2e79ef771a1d7c8abeb29eb633c659

So the above examples may be "long fixed by now".
Then again, maybe not, or not all.
notice that the above commit doesn't only try to make it so the
installed package is compiled correctly (which is admittedly the most
important concern) but also to make it so the running Emacs session is
upgraded to the new package without having to re-start.
