It would be nice if every application in the world didn't have to hack on support for X number of different almost-identical storage vendors who all decided it would be better to have completely incompatible interfaces.

NFS isn't horrible, though it's limited. OTOH object storage is limited but has some other advantages. So there needs to either be the latter as a standard that can be adopted by all vendors, apps and OSes, or a new standard that fills the gaps of what apps want.
