I agree. I'd prefer to have a predictable place for the cached files, independent of having to run Python to tell you where that is. Right; I don't see who would disagree with that. I don't see any conflict between “decouple compiled bytecode file locations from source file locations” versus “predictable location for the compiled bytecode files”.

The conflict is purely that PEP 3147 proposes the new behavior to be optional, and adds a flag (-R) and an environment variable ($PYTHONPYR) to change it. I presume Barry is proposing this out of fear that the new behavior might upset somebody; personally I think it would be better if the behavior weren't optional. At least not in new Python releases -- in backports such as a distribution that wants this feature might make, it may make sense to be more conservative, or at least to have a way to turn it off.
