I agree with separating those filters.
Those filters are used for different purposes, one is to avoid
the getuid callout, the other is to decide whether use the device
for multipath.
Merging those different purpose filters into one structure will mess
things up.
I think that the following rule which you proposed is simple enough:
o unneeded devices are dropped first by the invalid_drivers section
o First match of the filter section is used for each device like LVM2

Although I'm not sure it's necessary, I prefer to leave it.
I sometimes use devnode rules just for testing, like creating a map
including only a part of paths (not all-paths).
That sort of mapping is not possible without devnode rule now.
