Is there a tracking thread/RFC for the ability to depend/hotload rlibs open

I am wondering because I would love to make A project where I can hot-load modules form dynamic libraries
but... normal shared libraries can make traits hard to test for. this is why I wonder if there is a open RFC/tracking thread
(I just want to be able to do smth where I would have crate A which has traits/structs that are meant to be used as a ABI/API? for loading this. I would then be able to in my program search for all rlibs that depend on A. then from A I could find all structs that implement a specified trait X. Watch as there is some other way to do this that doesen't involve relying on rlib...)
