I think than breaking O(1) expectation for indexing makes the implementation

Python operates with indices.
I don't use indexing on strings except in rare situations. Sure I use
lots of operations that may well use indexing *internally* but that's
the point. MicroPython can optimise those operations without needing
to guarantee O(1) indexing, and I'd be fine with that.
Any non-trivial text parsing uses indices or regular expressions (and
regular expressions themself use indices internally).
It would be interesting to collect a statistic about how many indexing
operations happened during the life of a string in typical (Micro)Python
program.
