Taranis Plus SE 2019 Questions

[Inyahin]

Hello.

I'm thinking about buying a new transmitter; and the Taranis Plus SE 2019 looks like it might do everything I need and I have a few clarifications before I buy one.

Question 1.
I spend a lot of time on the sim practicing so I want to know if the transmitter will:
a) run off a power adaptor without a battery.
b) is compatible with the 6-in-1 USB adaptors that plug into the training ports on transmitters.
c) if not b; then is there some way to get it compatible with Phoenix Flight Sim?

Question 2.
I need s-fhss, devo and probably dsmx in the future; so the 4-in-1 multiprotocol adaptor looks like it'll do just the job, but everywhere I looked said the firmware isn't compatible; is that information out of date?
I can't find any up-to-date reviews of the 2019 model - but the ones from late last year all said that multi-protocal hasn't been implemented yet.

MPM has always been supported.
A battery is needed but the radio will feed and charge off of USB when connected.
Trainer port is standard.

I got a Radio Master TX16S in the end - hits all my requirements out of the box with a better price point.

I'm looking forward to a decade (or more?) of flying with it.

Thanks for your help.
