But you can look up the necessary symbols in those bundles and exec
the functions that way. Not as clean as we're (linux dso's) used too,
but load order isn't as critical, and you can test for the symbol,
load the necessary bundle and unload when finished.

I'm still fighting porting an application that expects several library
components to be both loadable and linkable. This means I have to
build both a dylib and a bundle, and the existing packaging structure
seems not to lend itself to namespace collisions.
