Actually, keep in mind the background of this thread when referring to "no one". We can talk reason to most, but not all. ;-)

OK. Now we are down to a managable set here and I agree that these are "close to the bone" as you name it.
The days of the XML extender are numbered, no secret about it. Call it deinvestment into a tool that has served it's duty. While it's a sore spot right now, I take solice in the fact that XML can't complain of lack of attention in Viper, being buried deeper into engine than any other vendors XML.
HP... interesting question. DB2 customers move towards AIX, not away to HP (remember that open letter to IB?M). So while support on paper would look good, not a common one to run into. Maybe DB2 is playing hard to get ;-)
Linux: I can't argue that one.

So boiling this whole topic down the question is: How popular are those extenders. that's a direct function for limitations DB2 for LUW does or does not place upon customers within it's supported platforms.

Apparently not popular enough to cause IBM significant headache.... Being stoned once every six months or so in this newsgroup is my headache not IBM's. ;-)
