If it increases the closure size a lot and does not provide much extra
functionality, the extra dependency (and the components that require
that dependency) is removed.  (Alternatively the ext/ scripts can be
changed to use the 'python' in $PATH instead of a baked-in 'python',
though such things are avoided where feasible for robustness).

Even if they are optional, adding python might be required such that
the _correct_ python is used when cross-compiling.  As a test, you
could try running "guix gc --references" on the timewarrior store item
-- if the output contains python, the ext/... is installed with python.

Probably most people would have python anyway, so I don't think it has
to be removed.

Looking at the output of "guix gc --references", it does indeed use
python from somewhere.
