Then the index doesn't get updated. It is very difficult to come up with
a directory that is known to be writable under Windows.

It actually doesn't copy. It makes symbolic links for most of it, so the
operating system is just referring to the files where they are. It is
necessary to modify the index to allow for HTML help for installed
packages (the limitation you noted for Windows), and it is simplest to
link the HTML files to the same directory to allow relative paths to work.
