I don't claim that this is necessarily an authoritative refutation of the claim that a T flip-flop must have separate T and clock inputs. It can be made from a J-K flip-flop by tying both of its inputs high. It is useful for constructing binary counters, frequency dividers, and general binary addition devices. The T or "toggle" flip-flop changes its output on each clock edge, giving an output which is half the frequency of the signal to the T input. However, when I google "T flip-flop", the very first hit that comes up for me is this which states: Someone has commented that this circuit is not a T flip-flop because the circuit depends upon the clock alone, and does not have separate T and clock inputs. Simulate this circuit – Schematic created using CircuitLab The circuit below simulates fine in CircuitLab. To implement an edge triggered T Flip-Flop that does not rely on gate delay timing, requires, I believe, a minimum of 6 Nand gates.
