Yes, if another transceiver manufacturer chooses to emulate Yaesu's
protocol (BCD based "band data" with 160M = 1, 80M = 2, 40M = 3,
30M = 4, 20M = 5, 17M = 6, 15M = 7, 12M = 8, 10M = 9 and 6M = 10),
they should also emulate the signal levels.

Icom and Kenwood have spoken, Icom used its own proprietary "Stepped
Voltage" for the IC2KL/IC4KL and certain antenna tuners (which Elecraft
supports in the KPA500 and KPA1500), while Kenwood have never provided
any "band Data" outputs.

I don't know/care what Flex are doing in their current "radios" - their
older products could be made to properly emulate the Yaesu Standard by
running a third party software application that drove an LPT port in
the computer that did the majority of the Flex's "work" - that LPT
sourced sufficient voltage/current (in "full power" ports) to be
compatible with the Yaesu implementation.
