There doesn't seem to be any way to silence pip's warning about experimental commands being removed without prior warning (ironic, haha) and it produces an unexpected error when PIP_REQUIRE_VIRTUALENV is set.
There doesn't seem to be any special flags related to ignoring this particular warning, this feature is not listed among the 3 valid values given by --use-feature error output.

WARNING: pip index is currently an experimental command. It may be removed/changed in a future release without prior warning.

Description
There doesn't seem to be any way to silence pip's warning about experimental commands being removed without prior warning (ironic, haha) and it produces an unexpected error when PIP_REQUIRE_VIRTUALENV is set.
pip index versions <module>outputs an "experimental command" warning when called directly, when called as a python3 module (via-m), whenPYTHONWARNINGS=ignoreis given, or-Wignore(or both!)There doesn't seem to be any special flags related to ignoring this particular warning, this feature is not listed among the 3 valid values given by
--use-featureerror output.Expected behavior
