The -devs are for on device development and you can do that if the
device is up to the job resource and connectivity wise already (see
Poky's sdk images).

The packaged staging packages and the -dev packages have a lot of
overlap and some have suggested using -dev packages directly but it
isn't quite as simple as that, I won't bore you with the technicalities,
its all in the OE list archives.

Agreed. I'm just trying to show this isn't difficult and not as far off
as people think. Package dependencies in the toolchain work in Poky now.
If it works in Poky, making it work in OM is pretty trivial, then it
just needs documenting.

It really depends who imports the changes into OM since thats the main
obstacle in some cases. I can see all of the things I've mentioned
happening relatively soon, say the next couple of months.
