This sounds like it'd be exactly how I currently use Tumbleweed on my workstations: I don't update daily, but rather every once in a while. I appreciate the new versions of things, but being on the daily bleeding edge is more work than I care to put in.
I can also see this working quite nicely for those with nvidia hardware, where with TW you'd sometimes end up with a kernel too new for the drivers to get shoehorned in. A slightly easier-going pace would help there.
It also reminds me of Android, where you have roughly monthly updates (theoretically) and every now and then a bigger one.
