> So how can you keep generating disposable software on this layer?

Well... If your "users" are paying customers of a XaaS Subscription service, then there's propably little need and/or room for disposable UI.

But if you're doing something for internal processes with maybe 2-3 users at max, then you might want to do something that does not result in launching an under-budgeted project that could be a full blown SaaS project on its own.
