So, it's not just me!
I inherited a Hoya skylight filter on a second-hand lens and have
noticed that it's hell to clean. I thought maybe it'd been damaged or
had gotten some kind of residue on it, but never noticed any effect on
my images. Still, whenever I've spotted a smudge on it and tried to
clean it, it's always so stubborn that I'm afraid I'll damage it with
all the "scrubbing", as it were.
In that case, I agree. SMC coating would be nice.

For as long as I
can remember people have been complaining about Hoya's HMC filters;
not their effectiveness but rather how difficult they are to clean.
