With Maildir a dovecot-shared file controls if the \Seen flags are
shared or private. The file must be created separately inside each
Maildir, although if the file already exists in the Maildir root it's
automatically copied for newly created mailboxes. If dovecot-shared file
doesn't exist in Maildir, the \Seen flags are shared. If it exists, the
\Seen flag state is stored only in the user's index files. By making
each user have their own private index files, you can make the \Seen
flag private for the users. For example:

namespace {
  type = public
  separator = /
  prefix = Public/
  location = maildir:/var/mail/public:INDEX=~/Maildir/public
  subscriptions = no
}

Now when accessing e.g. "Public/lkml" mailbox, Dovecot keeps its index
files in ~/Maildir/public/lkml/ directory. If it ever gets deleted, the
\Seen flags are lost.

If you want to change what flags are shared when dovecot-shared file
exists, currently you'll have to modify the source code:
src/lib-storage/index/maildir/maildir-storage.c maildir_open() has
mbox->ibox.box.private_flags_mask = MAIL_SEEN; Change the MAIL_SEEN to
any flag combination you want. See src/lib-mail/mail-types.h for list of
valid flags.

however if there is a need for some new/debugged/better features relate
to what you asked you have to upgrade to latest dovecot
