Excess cREVGeometry profiles a problem?

[Frank Leahy]

I wrote a routine to list the custom property sets for every object in 
my project (as part of getting ready to ship), and noticed that quite a 
number have a "cREVGeometry" property set, even though I don't use the 
Geometry Manager anywhere.

Can anyone tell me if these are problematic at all?  Should I be 
deleting them if I don't need them?  (And there doesn't seem to be any 
way to delete these in the GUI, I'll have to do them programatically.)

Thanks,
