They are supported as comments. I am not sure if there is a use case that goes
beyond displaying "on appointment" to the user (see below) that would require
this to be directly supported by the syntax. If there is, here is a discussion
about it:

When it helps the average mappers why not. I (un)fortunate am too much involved
in the opening_hours syntax to speak for the average mapper in that regard.

I always understood comments in opening_hours as comments intended for the end
users. It is true that currently most services or programs that evaluate
opening_hours do not display them but I consider that as a bug of that service
or program which eventually gets fixed. http://openingh.openstreetmap.de/ does
display comments to the end user for example.
