<space><space><tab><space>
is different than
<space><tab><space><space>
So you also have to track the actual sequence of counts of white space used for each level, rather than just a simple count.

in my view, both are the same, both `is` (or ===) an IndentationError raise

It's just a stack containing strings at the end of the day. Really not a big deal.

For a 1024 byte implementation (and even way more complex impl.) You would just force one whitespace char, and definitely no mixing.
Or you just forbid mixing spaces and tabs in the same indentation sequence, the way most whitespace-sensitive languages seem to end up doing. Or you make a slightly more reasonable rule: spaces may follow tabs, but no tabs may follow a space. That's at least unambiguous.
