Python has no 'case'; 'elif' is just one of the clauses that an 'if'
statement can have.

Python has no 'do...while', and its for and while statements have
drastically different semantics.

Fattening the language up for 'convenience' is generally not the Python
way.

My reaction is one of utter revulsion, for what it's worth.

Python did not get to its incredible success of today by basing its
design decisions on "popular demand", which appears to be an even
crazier notion than "design by committee".  Design by a committee tends
to produce a lot of bloat; design by "popular demand", i.e. a group of
people substantially larger and less selected than even a committee,
would no doubt produce even more bloat.

If you want bloat, go use a bloated language (there are so incredibly
many of them, that you'll have your pick!), and please leave alone one
of the few languages that have managed to at least control the amount of
cruft they have accumulated over the years (we keep hoping for a REMOVAL
of many legacy features come Python 3.0 time, in fact).
