It's not even that. It's required for the standard library, and not at
all a language recommendation elsewhere.

Ah yes, and then you have these massive source control diffs when you
do a meaningless conversion over large slabs of the code! Perfect,
just what we wanted.

For teams that disagree on the correct width of indentation levels,
why not standardize on a single token meaning "indentation level", and
then allow everyone to configure their editors to show it at whatever
width they prefer?

Yes. Make sure you use an email client that supports leading
whitespace of all forms. Otherwise you're not going to have a good
time of it.
