So? Just "make; make install" and you're done. Or "apt-get install foo".

You mean, something to replace "make install" if it's not installed on
the server? Fair enough. You could probably write a little perl script
to parse simple Makefiles that only copy a few static files in place. Or
add a flag to the control file indicating that the extension follows a
standard layout, and doesn't need a "make" step.
I fear we're wandering off the point again. So let me repeat: It must be
possible to install the same extension the way you do today, and using
the new mechanism.
