A solution might be to look for the presence of the cache directory, and only look for a .pyc in the source directory if there is no cache directory. Testing for the cache directory would only have to be done once per package and the result remembered, so it would add very little overhead.
I think the other thing that bothers me about continuing to support pyc-only imports, is that people will then want tools to create them. Right now, it's probably just as easy as byte-compiling everything, then finding the .py files and removing them.
After PEP 3147 is implemented, and the default, you'll have to byte-compile the files, then find the pycs in the pycache directory, move them up a level and rename them. Then of course remove the .py files.
It's not insurmountable of course, I think if we support pyc-only imports, people are rightly going to want us to write and support the tool to create those imports.
