Yes, I do believe that that’s the way forward.
There was an effort started with the collaboration between ownCloud and WD Lab on a “PiCloud” which should have brought an official snap, but the 1st version had performance issues and that effort has stalled due to the lack of interest from users and resources.
The current Nextcloud snap from the app store is basically the same one, provided by Canonical.
I have no doubt that things will improve though as anybody can create a Snap or adapt the current one, so a team of volunteers might one day be assembled to work on that or NC could allocate resources to develop an official version or fund the effort.
