The programmers and other developers working on the MSQ revamp likely are not the ones who work on housing related content.
A raffle system doesn't change things for the better. It just changes the nature of the RNG involved. You're still going to end up with one winner and dozens of frustrated losers because there are not enough houses for every player that would like to have one.
Ishgard housing opening will help (even if it's just a continuation of the current system) but it will not solve the problem because there will still be more players per world than houses per world. The only thing that will solve the problem is an instanced system that allows every player and every FC to have a house if they want one.
