dovecot - Dec 2012 - Non-standard fields?

Hi,

Non-standard fields are mentioned here: 
http://wiki2.dovecot.org/MailboxFormat/Maildir and they are stated as 
currently not used.

Questions:
- am I right that if they will be used, they will be key=value pairs, 
like fields in the base filename? Like:
     1035478339.27041_118.foo.org,S=1000,W=1030:2,S,X=12,A=something
- or are they supposed to be flags, like: 
1035478339.27041_118.foo.org,S=1000,W=1030:2,S,ABCD
- are there any plans to utilize these?

Thanks,

I think both would work.

No. Other Maildir tools would probably break if they were used. Dovecot's
extra maildir metadata is placed to dovecot-uidlist file.
