Suggestion for argparse: raise a warning on type=bool #126676
Description
Feature or enhancement
Proposal:
There has been complaints about type=bool usage in argparse: #81745 #83348 #71181 . See also https://stackoverflow.com/questions/15008758/parsing-boolean-values-with-argparse
while we may not want to actually change the behavior (given existing code on the wild might use it, as mentioned in previous discussions), what about raise a warning? Or is that also too intrusive?
Has this already been discussed elsewhere?

I'd probably be more inclined to document recipes/patterns to achieve the desired result if we need additional materials here since we have already documented that
bool()is not recommended as a type converter.My concern is that adding a warning here could still break tests, etc.
