No, but I think it should be clearly stated in the description, if there are any sepcial requirements, that differ from the ones stated in the Nextcloud documentation. Ideally, you would even be able to filter by requirements like PHP version, database, Nextcloud version etc.
On the other hand, this really seems to be an exception. I have never heard of any other app that requires a specific database. Although there is at least one app, (I think it’s the Passwords app), that requires a higher PHP version than the minimum version listed in the official Nextcloud Server Requirements.
