Fixed target vault size

I proposed something like this a while back:

SAFE Network Dev Update - August 30, 2018

Would it be easier if vaults came in fixed sizes? It would be trivial to measure the free space ratio. As my (not fully confident) understanding goes, chunks are assigned to sections by their XOR distance from the section ID, which assures that chunks are uniformly distributed across the sections. If the number of vaults within a section falls within a narrow range, then it would make sense to make each vault responsible for roughly the same number of chunks (well, a given number of chunks; v…

Vaults could come in a series of fixed sizes. It would simplify the economy as @mav already mentioned and, if the size depended on the age, it would also lessen the loss if younger, thus less reliable, vaults disappeared or misbehaved.
