As long as wifi over USB is supported, why overcomplicate the core hardware? Sell a dongle as an add on option and make a little profit from it.
Completely an aside: USB dongles piss me off; specifically the Logitech Mouse USB dongles: Why the heck hasnt a single manufacturer included the USB Dongle radio IN the mobo? So with slim laptops you have few USB ports. I currently am typing this on an HP Omen flagship gaming laptop...

Anecdotally, I've experienced very few issues with the Logitech MX Master (both the original and v3) on my Mac via BT - every once in awhile (often enough to be aware of it, but infrequently enough that it's not something I'd consider a problem) the original would cut out for a few seconds, but other than that it tracked perfectly, and I haven't even had the periodic cutting-out issue with the Master 3 (yet; I've only had it for a little over a month now).
Of course, this is dependent on the BT implementation of both the mouse and PC being used, which is something to take into consideration (I've had way fewer BT connection issues in general with MacBooks than with any Windows laptops).
