I however want on-demand loading of modules from shared libraries for a
different reason.

As the maintainer of the debian package of exim I get a lot of mails asking
me to compile in the mysql and/or pgsql lookup drivers (normally mysql - I
don't know why it's more popular than pgsql but it does seem to be). I would
like to; debian policy says that I should compile in all optional features
unless there is an over-riding reason not to.

In this case there is what I consider to be an over-riding reason not to:
exim is a priority "important" package[1] and including those lookup drivers
woudl bring two big databases, or at very least their client libraries, into
important, which I don't want to do.

minimum of commonly-expected and necessary tools."
