FYI - I have specified that the squares NOT straddle over all-layer plane
splits ... for example, splits for Ethernet isolation, where you really
don't want coupling between the two sides.
On the theory that anything straddling the split forms a tiny HF capacitor
across the split, we put a keep-out area along the split and made sure the
thieving pads obeyed the keep-out restriction there.
If we hadn't done this, the capacitance might have been less than that of
the normal Ethernet isolation transformer; but anything you can do to help,
is probably good.
