I think that so many users have a hang-up about fillets is because in most other CAD packages (and I’m including Alias here, so not just parametric solid modelers), it’s very easy to add, change and remove fillets whereas in Rhino, it’s an extremely time consuming hassle.
Also, fillets are quite often used in mechanical design whereas lofts are used for aesthetic design. With Push/Pull being a thing in V8 now, hopefully the next logical evolution are fillets which can adapt to Push/Pull changes. And then if the fillets could even survive the drafting stage, that would be heaven! 
But then they’d finally have to do something about this (which would again benefit us all)…
