The reason I chose divisible is because I was
attempting to not introduce all-out math into
conditionals.  Divisbile is obviously useful to create
a form of cycling, say wrapping a table after every
third column  (:if divisible {$PageCount} 3:).  It was
a good start, but there were still simple formatting
things that were not possible: using the same
scenario, wrapping every third column, what if you
wanted to set a different color to the middle column? 
You would probably need some form of generic math
framework, probably more than what you want in pmwiki.
 I just figured I'd mention this type of limitation to
divisible now since you are potentially thinking of a
more generic solution. :)
