I was assuming, judging by your own comment, that the non-free plugin
is pragmatically important enough that the package ought to declare
"Recommends" against the non-free plugin. In that case, Debian policy
(2.1.2) prevents it from being in main.
Remember, being in main is not a goal or honor in itself. The
distinction between main and contrib is that we promise our users that
software in main will be genuinely useful *without* looking outside
of main. If that is not the case, putting the software in main anyway
will just amount to cheating our users.

Linking and (this meaning of) loading are really just two words for
the same process. Rememer, e.g., that the system linker is called
"ld" - which is short for "load". And in a very real sense,
dynamically liked binaries under Linux do indeed "load" shared
libraries rather than being "linked" with them. Look up the man page
for ld.so(8).

Yes, you're missing exactly the difference between LGPL, which is that
the LGPL does allow linking (loading, foobaring) with softare under a
different license, as long as the user has the means to change the
LGPL'ed part of the software.
Anyway, it this bothers you it will probably be a relatively simple
matter, techincally, to rewrite the LPGL'ed application such that it
is a conventional library that is invoked by a user-specified main
function, and then writing a BSD-licenced main module that links
traditionally to the plugin *and* the LGPL library, connecting them
to each other. However, the very triviality of this exercise is one
reason why I don't it should be considered different from a licensing
standpoint.
