Possible to separate out tk from python?

[John Kehayias]

Hi Guix,

Quick(?) question if someone happens to know: can we separate out the tk 
dependency from the python package, for instance by making the tk output of 
python a separate package?

I'm asking because I've realized that it is through tk that python, and thus a 
good chunk of all packages, depend on things like libx11 and xorgproto. In 
updating xorgproto for xorg-server-xwayland update, this causes python to be 
rebuilt. I saw the same when ungrafting libx11 but didn't look close enough to 
realize it is through tk.

(As an aside, in using python as a user, it is easy to miss the python:tk 
output when you need it. And without searching I'm guessing many fewer packages 
depend on python:tk than the default output.)

I don't know enough about how python is built (and then used in building) off 
the top of my head to know if this is possible. But if it was, I think it could 
untangle lots of the package graph.

Thanks in advance!
John
