[ ipq807x is questionable at the moment, considering the discussions
  around adding ethernet/ switch support for the ax3600. ]

At least these targets have- or are in the process (lantiq) of getting
DSA drivers, but that doesn't mean all of the supported devices do (e.g.
ath79 comes with a variety of different switch hardware, especially the
older devices) or that the DSA drivers would be good enough to take over
right now (e.g. ASCII encoded MAC addresses for ipq806x --> ea8500/
nbg6817 with qca8k or the current state of lantiq's DSA drivers, which
are still under active development).

Assuming that 20.xx is supposed to be branched off 'soon' (and defining
"soon" to be within the next couple of months), it's probably not
feasible to migrate additional targets over to DSA right now, even for
the devices where drivers exist, as this would invalidate all testing on
these devices. IMHO this would be more of a todo item for immediately
after 20.xy.0 gets released.
