I don't care for it.
A word doesn't stand out like a character does, plus this usage of pass is completely different from its normal usage.
We're already used to interpreting '*' as a coin with two sides, let's stick with it:
def apply_map(map, target, *, frobble): # '*' means frobble is keyword only
...
and later:
frobble = some_funny_stuff_here()
.
.
.
apply_map(map=kansas, target=toto, *, frobble) # '*' means frobble maps to keyword frobble
