Honestly, it's very reasonable and even responsible to wait a bit (a week or two perhaps) before using a new version, especially given that 0.19.5 came swiftly after 0.19.4 due to some bugs. And of course anyone running a fediverse instance is a volunteer so it's probably not reasonable to put deadlines or pressure on themselves. But I won't speak for the admins on programming.dev and of course asking is perfectly fine, just don't expect an answer :)
