indeed deep down counters are used for a few (but not defined in the 
usual range); the main reason is to make sure that (at least for now) 
old code that expects a counter still works ok (as i have no clue how 
abstract macro package interfaces to this pdf stuff are) ... so maybe 
later that low level thingie will go)

anyway, the split in the three categories made it possible to nicely 
regroup the related code (so that we have a cleaner core code base, a 
bit more more close to original tex, not mixed with backend related 
checks and primitives in inconsistent ways)
