I would say "Yes, if specific enough".
Most SE sites don't allow recommendation questions, but there's a whole Software Recommendation SE that's specifically for it. While they're good at finding software over there, it's a fairly low-traffic place and the kind of question which would be asked here is likely to be very specific, with answers talking about little-known software. We can do a better job of answering world building software questions internally than by pointing people over there.
That said, we need guidelines, and I think theirs are worth adopting, at least as a starting point. (See image, here, and here.)
A good question would state what the intended use is (world generation, naming, knowledge maps, etc), what kinds of features it should have (random generation from a seed, word lists, smart linking, etc). A good answer would address that use and those features and ideally include something of a personal review of the software.
