The proper way to detect the presence of shared seen state is the

Check for ANNOTATEMORE in the CAPABILITIES
If not present, then no shared seen state.
Otherwise,
GETANNOTATION <mboxname> "/vendor/cmu/cyrus-imapd/sharedseen" "value"
If you get an empty response, then no shared seen state. Otherwise, the
value will tell you if its enabled on the given mailbox.
This would answer the wrong question, we want to detect if the server is able
to run in shared seen state. if it does we can offer a configuration option,
otherwise we do not.
I do not know if there is a different test method that could answer this
question. It is not feasable to try to set the annotation on a test folder
for each connection IMO. So best would be if there would be a SHAREDSEEN
or so capability.
I would support standardizing of such IMAP capability.
