Do the indexes contain any of the header information?
Yes.
In particular, since I know nothing of the communication between IMAP clients & servers in general, is the information that is shown in typical client mail lists (subject, sender, date, etc.) stored in the indexes?
Yes. Dovecot adds to cache file those headers that the client requests.
I guess I'm asking if any planned changes will have an impact in retrieving message lists in any way.
Usually not. Unless client fetches the entire header. Some do I think, but usually not.
