Are there security implications I have missed that would be triggered if
you treated dynamically loadable chunks the same as the -C <config file>
option?

So specifying a loadable module on the command line drops privilege in
the same way as a config file change.

BTW are we really talking about making everything loadable, or is this
really useful only for lookups? AFAICS lookups are currently the only
things that have significant reason to be separated out - not so much
due to the code size itself, but due to the libraries they pull in and
the dependencies they generate on exim (so a system ends up requiring 4
database libraries when it only uses one of the databases).
