ok :-)
What I was writing about has nothing to do with data models. (As usual, we successfully forgot what we have started from :-)
With data modeling the situation is much simpler (almost obvious) so *if* you need it you can get it. But frankly speaking I agree with you that there is no necessity to replace RM if people are satisfied with it.
>>infinity has to be reachable
You still think in terms of numbers and arithmetic operations like several thousands years ago. Numbers is one possible interpretation of what we see (very simple, natural and productive but somewhat limited) but things we see might have other interpretations. In particular, it is not possible to reasonably explain many phenomena including but not limited to infinity.
