I am a heretic then.

Except for the initial dogma, I understand and agree with the rationale
in coding-style.rst.

Only what if I have stared at the screen not for 20 hours, but for
40 hours? Now I want to have indentation even deeper, of 16 spaces.
And how do I get this having 8 spaces here and there instead of tabs?
The system begins to fall apart.

The misleading statement is that tabs are 8 characters long. No. They
are exactly 1 character long. And that's ASCII 9.
