Yes!

The main change is in python3-dir.bbclass, and the recipe tweaks
are just adaptations to the fact that only ${PYTHON_DIR} is needed,
not ${PYTHON_DIR}${PYTHON_ABI} from that point.

I was thinking that the introductory mail stressed this enough.

FWIW, less than 30 recipes was spelling the latter out in
openembedded-core and meta-openembedded combined.
