I just wonder how, then, the ``@option extract-in-place'' is implemented
and why is it not used by default...

I'm not so certain of that, as a matter of fact. My last attempt to
enhance pkg-code is still waiting (after two months) in the bin/34628:

It is certainly possible to extract only the controlling (+CONTENTS?)
file(s) to read the PREFIX and extract the rest under it. We don't have
to provide for non-seekable package files, do we?

But even without that, something under the /usr/local or /usr/X11R6 is a
better guess than /usr/tmp or /var/tmp...
