I've just replied to the patch. We did once consider extending meta-
toolchain this way however we also found it simply does not scale.

For example, you can have users add/remote packages but what happens
when they want to build a new package? Or build a new rootfs?

We found that whatever we did with meta-toolchain, we were going to
have to duplicate code that the core system already has.

For that reason we created eSDK and I'd much rather someone started
with that and put wrappers around it for the common use cases
(something like devtool) so that the user doesn't need to use bitbake
(even if it is used for some things behind the scenes).

Cheers,

Richard
