You mostly got it, yeah. Point 1, ECC is only also broken after Q-Day. Hybrids obviously help if you believe Q-Day is far into the future, or never coming. But if you take Q-Day happening as possible in our lifetime, the HNDL threat means data being encrypted today depends entirely on PQ security in the long run (since breaking EC with a Quantum Computer has an attack cost of like 2^30 or so instead of 2^120 or so).
