Interesting approach. Regarding the linuxacl and linuxmount modules: how 
do you handle compatibility across different kernel versions? Since some 
of these APIs (like Landlock or newer mount features) are relatively 
recent, does the library provide graceful fallbacks or just raise 
NotImplementedError?

Using sets of enums instead of bitmasks is definitely 'The Pythonic 
Way'. It makes the code much more self-documenting.
