Description

As discussed in #5511.

I still think that 2.14 is good enough. Especially since this is a test decorator and won't impact performance of a plugin directly.

Actually we might need to check the TODO before releasing because it's easier to forget about that. Maybe upgrade the #5513 type list when we add todos ?

Because of argparse I'll need to do a full review of all TODOs anyway. But I'll add that to the list!
