Deprecate sysopnames

A future patch will removed all of its use cases.

Sandbox variables are deep copied instead of shallow copied because
for some reason family registration prefill 'sysopnames' with empty
dicts for each family, breaking recursize dict comparison, since the
objects inside and outside of the sandbox refer to the same object.
