Creating the -dev and -dbg packages for task packages is intentional.
The python code to create the RRECOMMENDS you mention already exists in
the form of depchains in package.bbclass.

I know this works in poky as its how we create development and debugging
images, I can't remember whether it was enabled in OE.dev or not but the
code is there...

Also, not all task packages are PACKAGE_ARCH = "all" although I guess
they'll be explicitly marked anyway.

Cheers,
