Doubt it. It’s been discussed before. Folks are bitter, and rightly so, but that’s it.
The reasons why questions go unanswered are probably too numerous to list. Look at this person, they’ve been around for 6 years, apparently, yet they’ve answered no questions: 
~19% resolve rate
It’s probably a bit higher → people do not click the solution / resolved / close button. And the metric covers the venerable (migrated) Answer Hub content whose button was pretty hard to find 
There are also questions so in-depth that cannot be answered by a mere forum dweller and the sinfully repetitive ones no one bothers to click on.

On a more serious note, I’d say it’s the latter. Chances of attracting an individual with the pertinent know-how may be slim. BP traffic is an order of magnitude higher than C++. You may need to wait more than 13h is some cases. If you haven’t received an answer in 3 days, I say bump it.
Imagine if there was a system where you could earn tokens that would allow you to fire a tough question at Epic’s engineering team who must dedicate 30m per week to forum duties. #crazytalk

Also, try the same question on Reddit / Discord, it’s quite lively out there.
