That's not a particular JunOS "feature"... too many combinations of 
options to fully test, so when something fundamental is rewritten
(because it is so rotten it needs rewrite), some combinations will break.

My problem with this is more "we're too small to build a lab that can
really test all possible combinations we have on one of the various
boxes in the field", so we test fundamental things, deploy, and despair...

(The other issue is that sometimes vendor TACs just don't understand
why some behaviour is totally broken...  "the developers say this works
as designed")

"If was one thing all people took for granted, was conviction that if you 
 feed honest figures into a computer, honest figures come out. Never doubted 
 it myself till I met a computer with a sense of humor."
