Title says it all. This also implies updating importlib to use sys.implementation directly.

Adding patch. If I misunderstood the issue, let me know.

I ended up applying Eric's patch from #14797 and then comparing against Jeff's patch here since Eric's cleaned up the C code. Thanks to both for the work!

I meant issue #13959 for Eric's patch; wrong tab. =)

One small thing: this comment from import.c was not copied to sysmodule.c and is now deleted:

-   TAG must change for each major Python release. The magic number will take
-   care of any bytecode changes that occur during development.

Good catch.  However, do we need that comment?  The tag is programmatically derived from the version (in Python/sysmodule.c).
msg164561 - (view) Author: Éric Araujo (eric.araujo) * (Python committer) Date: 2012-07-02 22:39
Ah, good, if it’s automatically derived then we don’t need the comment.

There was some concern with PyImport_GetMagicTag() extracting its value from sys.implementation.cache_tag.  I've addressed this in issue15242.
