This question is hard to answer, because there are actually 2 questions: do i want them to skip 9.3: YES. Shadowlands was already a bad idea itself, it was also executed quite badly and all in all the maw is probably the worst zone they have ever created; it's like crystalsong forest, just with less lore.
But do i want that 10.0 come out earlier? Not really sure: i rather want them to focus on new content so that there is actually playable content; and not the kind of: More dungeons and raids, i want them to bring good solo content back like Suramar. This was phantastic content without relying on: hey, let's visit the old stuff and do exactly the same s*** again that you did while leveling, aka world quests.
A whole ENDGAME zone for ENDGAME progression with the first REAL city in WoW. That was good content, not a hole like the maw with nothing inside.
