The limit would be fine if the team released the votes after composing a list of voted upon topics. Maybe release the votes Quarterly. The update could even detail features the team have chosen to add to the roadmap with a potential timeline in terms of priority.
Otherwise 24 really isn’t unlimited as some votes have. Tied up for over a year and possibly more. It is a pain to also try to go and remove votes in seemingly dead features that might not even being considered.
