If somebody types in './tools/build.py -mrelease' he expects everything to get
build. Why do you want to change that behaviour?

This was a personal request from Dan, which is why I cc'ed him. He wanted
api_docs removed from the default build to make it faster, which is why I
commented that I'd prefer to make the default just the create_sdk (and some
others) so it's faster.

Actually, I'd really like our gyp targets to be cleaned up so that the
dependencies are as minimal as possible. Having all gyp files in a common folder
would be nice, too, but no hurry.

Yes - this was primarily for the VM team, but also to speed up our build process
in general. No one looks for these docs or uses them from their builds, so
removing them from the normal build will make people's lives better.

To which I ask, do most people need the editor? Or samples? Etc.

probably not, but this step takes so long that it stands out. If you do a
debug-mode build, this step easily takes 5+ minutes.
