I would support this for apps labelled as official. For independent app developers, they often just build an app for themselves and share it with the community. They do some testing based on their setup, if you force them to test all the imaginable combinations of different php/database whatever version, they just won’t publish it. (And there is oracle support but just for enterprise customers, that is not testable for standard-users).
For me the better way would be to get some support from the community, however some developer with existing experience in the Nextcloud environment, that is difficult. Perhaps a hackathon or something like that could be a good occasion to tackle such issues…
