Lossless is relevant regardless of what some objective measures say or what even a blind test says. The entire audiophile community is the evidence. They can also point to measurable distortions and debatable issues in the audible spectrum when compression is at play.

Also I can't connect more than 2 devices to my Bluetooth device right now, and even that is very new. That's a lot less than 10. The point is we need to be able to connect a full power speaker setup, audiophile grade headphones, a keyboard, a mouse, a dac/amp stack, and a webcam all at once with low latency and no interference and full bore uncompressed audio quality maintained on each device for audiophile products to move fully wireless. You won't ever convince audiophile diehards that their music sounds the same on Qobuz vs YouTube Music or Spotify on Bluetooth as is. We're not talking about a room full of 100 average people, we're talking about the one person in the room who cares. When the room has 8 billion people, that's still a market large enough to sustain wires for some time until a wireless tech can stream full bore FLAC without compression from an average phone.

"The psychoacoustic model provides for high quality lossy signal compression by describing which parts of a given digital audio signal can be removed (or aggressively compressed) safely—that is, without significant losses in the (consciously) perceived quality of the sound."

Significant and safely are the two words you should be reading there. It's not proven 100% of the original lossless file as its literally lossy and getting it right 'most of the time' as their model does, isn't the same as getting it 'always right'. So lossless is still obviously preferred.

I mean you're really taking the whole work out of context as it's designed to lose less of the recording than the data shrink would suggest, not provide a perfect match for lossless.

Not to mention the factors of the dac and amp portion of a tws, few actually measure 'perfectly' despite sonically transparent dacs and amps (such as topping) being affordable both as portables and desktop set ups. So wireless has a ways to go, that said by someone with both wireless and wired set ups.
