While of course memfd can be accessed quicker than disk storage that doesn't justify backing all the anonymous mappings with memfd. Even for executable images only it may be very lot.

In the other thread you are mentioning Proton patch doing something similar. I think that was motivated as a workaround for a specific problems with specific types of mappings and probably would be better to be changed.
