RFC-1991 defined sigclass 0x40 as a timestamp, and went on to further

When RFC-2440 came out, this extra explanation seems to have been
lost, as 2440 defines 0x40 only as a timestamp.  A sigclass for a
signature on a signature would be very useful.  Any chance to restore
this clarification in the next draft?

Yes, please. I plan to use this in a project in the not-so-distant future.

I know there are a few timestamping services for OpenPGP in operation
already -- are any of them using this now?
