Yes, I saw that, but we don't use them at all.

I was hoping some people of the cups project would do that... I do not
have time spare to dive thoroughly into this matter and produce a patch
that will work on any system.

Also it might be a good idea to implement a function that queries a
single printerqueue instead of all of them in libcups (if it isn't
already there). That would make fixing cups-lpd really simple.

Yeah, but some of us don't have the choice.
