[Dovecot] dovecot-shared

I'm confused about dovecot-shared.

If the file exists, \SEEN flags are NOT shared?

So if dovecot-shared exists, flags are actually private. The doc seems clear on this (albeit not worded very well). I only question it because intuitively you would think the opposite. If backwards compatibility is the reason for this reverse behavior, the file should have been named dovecot-private-flags. In fact that's a great name to stick a list of flags (one-per-line) that are private.
