Unfortunately, that fails when one person writes their code with tabs
set to 8, and another person reads the code with tabs set to 4. Code
that was hand-aligned with a mix of tabs and spaces doesn't align
anymore.

Sometimes I wonder if Guido would have saved a lot of debate by declaring,
long ago, that Python code would never allow tabs in it, period. Which may
be a bit extreme, I'll admit. :-)
