First point: DECIBELS ALWAYS REPRESENT POWER RATIOS.

What about the fact that a musical discrete-time sequence may
well not originate from any kind of physical system? Isn't dBFS
defined in analogy but not with reference to the relations of
electronics?

Almost all digital electronics assumes an impedance of one ohm
resistive. The reference power for dBFS is taken to be
FS(peak)^2.

That's a weasel that lets purists have their cake and
pragmatists eat it.

Aha. Well said ;)
