If you are looking to enable application developers, then the SDK
is the right way to go.

You could create an entire build appliance that runs in a VM (your
idea #1), but that adds overhead and makes those application developers
interact with the entire build system (versus just what they need
for their application).

There is also a project called CROPS that is about creating containers
with the toolchain and have build capabilities. It is similar to the
build appliance VM, but with less overhead. It is worth checking out.

As for the differences in the SDK install that you are seeing, it is
best to grab the details from the docs, the (e)SDK should be well
covered in the latest yocto docs.
