Well, I got a surprise in exploring: removing boot.scr
and ubldr.bin did not prevent booting. (Noticed by the
accident of ending up with one of them missing that I
only later noticed.) So I recorded a boot and:

. . .

So I've likely been been booting via UEFI for
some time via 2020.10 (or even before?), just
without noticing at the time.

The other implication is likely that what disabled
root-on-USB for my context was not the boot.scr
removal material but some (possibly proper) subset
of other material changed (extracted from
ports' main 0d6e5081eb00 commit cgit display):
