Since it's looking like in the long term the Mac version is not going to be able to maintain parity, I thought I'd check and see if Oolite works in WINE on the Mac. I have CrossOver 22 (a commercial version of WINE) and was able to successfully install and run Oolite 1.90. (I didn't test any OXPs because I didn't bother to update the connection to the Expansion Manager in the config file.) The game speed is excellent on my MacBook Air M1 - on a par with the Mac native version.
I normally don't play Oolite on my Mac these days so I'm not going to do a lot more testing of this but I thought it would be worth checking, especially if the multiplayer developments continue.
