Not quite.  Quoting Ludo' in that thread:

  "I think we should move tkinter*.so to a separate output of the Python 
packages"

And indeed:

  ~ λ guix show python
  name: python
  version: 3.10.7
  outputs:
  + tk: [description missing]
  + idle: [description missing]
  + out: everything else
  [...]

So there's no bug, you just never included tkinter in your environment when you 
thought you had.

Iinstead of

>guix shell -CN  python tk tcl -- python3 -m tkinter

try

  ~ λ guix shell -CN python{,:tk} -- python3 -m tkinter

'python{,:tk}' is bash shorthand that expands to 'python python:tk'.

I get a $DISPLAY error because this machine doesn't run X, but that implies 
success, right?
