So I wonder if we're maybe hitting premature optimisation with this

This is a problem for anyone wanting to ship a script that "just
works" across platforms.  I found a similar discussion about a python

is described above.

I feel like contribution to some sort of global effort in this regard
might be the best way forward, and then ensure dib uses it.
