I think it's reasonably old, 2.18 for the dot syntax.  Standalone
pitches as pitches instead of a music expression were in 2.16 already:

commit 19990fb15a31ecd45d18777166617d14f30feb73

    Make #{ c' #} and x=c' create a pitch instead of a NoteEvent
    
    Since the specification of a pitch without a duration in those contexts
    makes it somewhat uncomfortable to guess the actually used duration, it
    is unlikely that much use of a default duration has been made in those
    constructs.  In particular #{ c' #} would appear handy.

It's more of a problem that this kind of stuff just takes a long time to
make it into "LilyPond lore", the way people reflexively do work in and
combine stuff with other LilyPond features.
