The question is now if we should "propagate" tstate to function calls in the latest VECTORCALL calling convention (which is currently private). +1, for all the same reasons I'm +1 on passing it to C functions explicitly. (In short, embedding can be very painful when you have to manipulate ambient thread state to make Python code work, and this is a good step towards getting rid of that requirement.)
