this had been sleeping for a while. After talking to Dago, I have
branched gar/v2 for testing purposes [1] and made two changes.

1) Adjusted gar.pkg.mk to include a PYCOMPILE variable similar to the
other cswclassutils GAR variables. Simple so far and close to what you did.

2) Regarding the implicit activation of such a feature, I thought it
might be convenient to use a GAR category.mk file for it. This
category.mk activates python specific build/install targets, adds a
dependency to CSWpython and sets a couple of variables, amongst others
PYCOMPILE and _MERGE_EXCLUDE_CATEGORY to handle the .pyc/.pyo files.

This way, a maintainer who wants to package a python module, just sets
CATEGORIES = python and has sane defaults, including activation of the
cswpycompile feature. Furthermore the python maintainer can take care of
this category.mk file to have it reflect best practices and CSW defaults
for packaging python modules.

There is a sample build description for ZSI [2] based on these changes.
Diff of the changes to GAR is attached to this mail. What do you think
(keeping in mind that the specific functionality of i.cswpycompile
itself is another sub-topic)? Dago?
