Well, yes, but IMO that kind of question isn't asked here enough.
Well two thoughts on that.
1) if a poster specifies they would like a certain feature, why do we need to grill them to see if they really will use it?
2) Most of the time when people question the original poster's desires it is heavily biased by what those answering people feel is important or not-important to themselves even when the feature was specifically inquired about.
Now if you want to suggest an alternative and point out something like "but keep in mind that one won't give you weather sealing you asked about" that to me seems fine. Where as grilling someone about what they need or trying to tell them they may not need something to me comes across as a bit, ummmm, condescending or rude.
