ThinkPad T14s Gen 3 has a 6850U and is ~1mm thinner than T14.
You're right though, none of them are superthin (<15mm) like ThinkPad X1 Carbon or Dell XPS 13. Maybe it's not possible to cool these faster AMD CPUs in such a small volume? Nobody wants to type on a space heater.

It's an absolutely infuriating UX fail which seems to stick to Lenovo's business line for some reason. I wanted to throw my work provided T14 out the window so there's no way I'm giving them my money for this design failure.
Why can't they blow the hot air towards the back/display like most other laptops? Can you imagine Apple ever selling laptops venting the hot air on one side instead of out the back?
Even my ancient HP ProBook I had would at least vent the hot air on the left side, so at least us righ-handed users were spared, so Lenovo seems to be the last and biggest offendant of this "crime".
I'm sure intel is pumped that the term is being genericized.
