There was a problem hiding this comment.
This docstring needs to mention that the predicate also holds if the flags are unknown.
Incorporate that into the string naturally in some way.
(Actually, try to copy-paste the above sentence into Copilot as instructions, use o1-mini or o1-preview with the Copilot edit mode: Select the docstring in VSCode, press cmd + i, make sure to select the right model, and paste my above instructions).

Don't outright delete predicates like this. Instead keep the implementation but add a deprecated annotation, and add an explanation into the docstring as to why a predicate is deprecated.
Deprecated predicates gets deleted after a little over a year.
