I understood you to mean that different mixtures of tabs and spaces would 
work, so long as they were equivalent to the same indentation under the 8-
spaces = 1 tab rule that you cited.

In fact there is no such equivalence rule. Tabs are tabs, and spaces are 
spaces, and never the twain shall be interconvertible.

The fundamental problem was that Unicode was a mess in Python 2 that 
needed to be cleaned up. Since they had no choice but to break backward 
compatibility in that regard, they figured they would fix a few other 
things while they were at it.
