On the other hand,
for any users wanting to use this i n the future, if it is not there,
they'd have to implement the logic for themselves. If it is a "burden"
for someone in a sprint, looking at other implementations, and with
all the unicode knowledge/documentation around, it would be pretty
much undoable in the correct way by a casual user. Removing it would
mean explicitly "batteries removal".

If you get some traction o n that, at least consider moving it to  a
pure python function on the string module.
