dBFS has not got a damn thing to do with sine waves or reference levels
or anything in the analogue world.

Well actually *dB Full Scale*, by simple definition can be the *full
scale
dB value* of any digital OR analog system. It's use now is more commonly
connected to digital systems of course.

What is the full scale of an analogue system? Is it where it starts to
get nonlinear, where it gets really nonlinear, or where it stops and won't
go any more at all?

Right. With an analog meter it's full scale point is obvious. But power
supply limitations mean there is always a maximum point that cannot be
exceeded in any system. It gets a bit harder to define when you consider
power supply regulation etc. But as I said, it's the *definition* that
counts. not necessarily the real world practical implementations.
