No, that doesn't make sense. The situation you presented above was
removing "impossible to remove" components on an OS and asking if the
software still works. You don't get to call that a vaild test
environment if the test environment itself doesn't work in the first
place.

Actually, business has a stock answer of "Supported on Windows XP or
later, Mac OS X some cat, Red Hat version foo, SuSE...."

In general they target actual known platforms, and YES they get to say
"I cannot support Centos 4 on this" all the time.

Hoo boy what I would give for -euDNtv to take less than 3 hours on my setup ;)
