I added the code to load the driver in src/imap/main.c following the
example from dict-client registration. Modified the Makefile, etc, got
it to compile. But it seg faults when imap is run. Traced it to
src/lib-dict/dict-sql.c:

/* @UNSAFE */
drivers = array_get(&sql_drivers, &count);
dict_sql_classes = i_new(struct dict, count + 1);

So, the comments don't lie. It is unsafe. Looks like that is why the
dict-server is the default with the proxy backend only. I guess I'll
poke around more. Advice on how to skirt this would be appreciated.

Was all this already talked about on the list, hence no reply? I
couldn't find anything...
