Another option is to use a through-hole "component". The schematic symbol
has 2 pins, one connected to each net. The footprint has two (through-hole)
pads that are close enough to short (as described earlier). Place the
footprint stradling the boundary between the planes, so each thru-hole will
connect to one plane.

Agreed. This would be acceptable in many (if not all) situations, and if
appropriately implemented (by setting the pads' X-Size and Y-Size to zero on
Mid layers, and ditto on one of the outside layers (which is possible by
using the Padstacks feature), thus confining the (linking) copper connection
to just *one* of the external copper layers), could even permit the nets to
be disconnected (relatively easily) if so required, which could be useful
for testing or trouble-shooting purposes.
In some cases though, space could be at a premium, and as such, it could
sometimes be difficult/undesirable to place two holes in the PCB file in the
required location. And in some cases, such a connection (even on all signal
layers rather than just one of the external layers) might be unacceptably
inferior on an RF basis (i.e. undesirably high series inductance). So it is
probably not a solution that would always be acceptable. For all that
though, it is another option that could be used at least some of the time.
