Looks legit. Spike protein is not the only protein T-cells could learn about. It is even not a preferred one. F.e. T-cells attack adenoviruses mostly on penton protein which is a capsid one resided in places where spikes connected to capsid. Rinoviruses also successfully attacked via capsid proteines.
That is why 15-20% (or may be much more) of people can't get SARS-CoV-2 at all, even if such coronavirus exists. They just have T-cells that perfectly know how to deal with coronaviruses, and it is not a spike protein that is for some shady reason forced as only and most important protein that this coronavirus have.
Small note: Since everything about coronaviruses now is highly politicised and it is hard to find something objective, you could easily search same info on adenoviruses instead of coronaviruses, they are very similar, the main difference if a shape of capsid. Adenoviruses also has spikes, and all other stuff.
