No, indeed.

I still think we need to use RTLD_LAZY properly on systems that support it,
allowing us to hook in required modules from the appropriate module boot
routine.  This can be done without any change of format or introducing
incompatibilities --- except we may need to be more careful with data
symbols which need to be resolved when the module is loaded, and I haven't
investigated how much of a problem this is is.  It's possible there aren't
any inter-module dependencies of this kind (there are already some hooks
for this kind of thing built into the main module).

For the rest, I'm agnostic between burying something in the .so files (bit
hacky) or adding an extra dependency (.zd?) file (bit messy), which seem to
be the major possibilities.
