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.
