> As soon as the M1 Mac mini arrived, I tore it down to confirm a few things Apple didn't make clear. All M1 Macs come with Thunderbolt 4 ports.

I think there's some nuance and technicality to this, because even though the ports themselves could meet Thunderbolt 4 specs under different conditions, they don't in the current configurations. Apple deliberately calls these "Thunderbolt / USB 4" ports, leaving out the version number from Thunderbolt. One of the requirements of a Thunderbolt 4 port is it can drive 2 4k displays, which Apple is very clear it cannot in the current models. So, that alone makes these not Thunderbolt 4. I don't think anyone's tested the rest of the Thunderbolt 4 features to know which ones are and aren't present.
