Consider support "all" as an valid action for warnings.filterswarnings/simplefilter. #121163
Description
Feature or enhancement
Proposal:
During reviewing the #121102, I found out that all is actually supported somewhere, but this support is not complete. Since users of Python are using it, I think that deprecating this behaviour would be incorrect. The best thing we can do here is to extend the support.
Has this already been discussed elsewhere?
This is a minor feature, which does not need previous discussion elsewhere
