Yes, independant of any particular realization (no specified line width
etc.), but are you really claiming that it's independant of ANY realization?
How do you tell, then, whether something is "conceptually" a-with-a-macron,
if the item's actual identity doesn't matter? Could that last question mark
"actually" be a small kappa, despite it both looking like, being encoded as,
and being used a question mark? How about this "S" here? The logo printed on
my mouse? My left ear?
....I suspect you're rather trying to say there's a THIRD level of encoding
too, abov Unicode but still grounded in data - within the font-rendering

"Squiggle attached to the bottom of a letter" is certainly a concept - it's
just not limited to a comma and a cedilla. Not even if combined with
"squiggle with a hook to the left", nor "squiggle that represents a palatal
variant of a sound".
