Q:

Should we have a blanket question for "Is this hardware compatible with Ubuntu?"

I know shopping recommendations are off-topic, but I think "Is this hardware compat" or "What hardware is compat" could have a useful answer that links to the Canonical certified hardware page.  
A good question would be worded in a general way.  A good answer would make it clear that there IS other "working" hardware, but that asking if each individual piece of hardware works is off-topic.  If you want to be sure, buy certified hardware.  
Just today at least three questions have come up for close-vote based on this.  I think it might be more productive to dupe them to a sort of "FAQ for supported hardware" question.  
Should it exist?
If it does, what is the canonical question/answer?

A:

Many possibles:

Up-to-date hardware compatibility lists
How do I know if a laptop will work with Ubuntu?
Which hardware manufacturers are more friendly to Ubuntu, besides Intel?
deleted question

Pick one.
