More often than not, in opening a junction box, esp. the larger 5" ones,
I'll see oodles of neutrals wire-nutted together, irrespective of the phase
of the hot leg. Apparently there is a wide-spread cavalier attitude toward
the lowly neutral.

More likely IMHO a failure to understand that the neutral carries current.
It's a Code violation, and a dangerous one, to connect the neutral of one
circuit to the neutral of another circuit unless the two are part of the same
multiwire circuit.
