If .pyc files are to be shared, it seems essential to (by default) generate them at install time and make them read-only for unprivileged users.

I think in practice this is what's almost always going to happen for system Python source, either via your distribution's installer or distutils. I think most on-demand creation of pyc files will be when you're developing your own code. I don't want to have to run a separate step to get the benefit of pycache, but I admit it's outside the scope of the PEP's original intention. I leave it to the BDFL.
