Honestly, just because the subject matter is relevant and useful to UX practitioners, that doesn't mean the question is a good fit for Stack Exchange.
The whole format of Stack Exchange is for a specific question to be asked based around a single problem that needs solving, and for people to provide the correct solution to that problem.
The whole UX.StackExchange site - and Stack Exchange as a whole - is a repository for problems that other people may also have at any point in the future but haven't been able to find the solution for.
"How can I get X to do Y?" is a question that will have a correct answer today, and that same answer will be correct in 5 years time. "What is the best piece of software to design a UI?" is a question that may have a subjective 'best' answer today, but in 1 years time there could be a totally new piece of software that does everything that one does, but much better. Or that other piece of software could have been discontinued. So the question will be out of date (assuming the subjective answer could even have been considered 'correct' in the first place).
Jeff Atwood (co-founder of Stack Exchange) wrote a blog post about these 'shopping request' questions way back in 2010. It is still relevant today: https://stackoverflow.blog/2010/11/23/qa-is-hard-lets-go-shopping/
