Two things. First, some economists study stated versus revealed preferences. [1] The idea is to figure out what people do rather than what they say they will do.
Second, in the case of people making feature requests, it could be a net-societal-gain [2] if feature requesters made some kind of binding commitment. (See also the hold-up problem [3].) Perhaps a potential customer would commit to "if/when feature X gets added, I will commit to using the product for 2 hours." or "... I will spend $10 on the associated cloud services." (The question of what happens if the customer reneges also has to be agreed upon up front.)
