So the kp-7 vs kp-home choice is done at a low-level, as expected.
So adding remappings like S-kp-home => S-home to function-key-map is
a good idea.

[ Of course there's the question whether S-kp-home should be turned
  into `home' via `kp-home' or via `S-home'.  ]

These are very different remappings, which seemed to be aimed at
reimplementing what your low-level keyboard code already provides.

Yes, probably.
