While I understand that electricity (depending on how it is produced) is a "clean" energy, isn't it better to hedge your bet and rely on oil or gas heaters in case the electricity conks out? Imagine being stuck in a blizzard with the grid knocked out, in freezing temperature. With an electric heat pump, you'll need to buy a generator as a backup safeguard.

Why are you attributing being stuck to a grid to electricity and not oil or gas? It is far easier and cleaner to generate electricity in a distributed fashion (yes, even by burning oil and gas) than to be free of the oil and gas supply chain.
Oil and gas can be stored and also acquired more easily. It just seems prudent to rely on more than 1 source of energy.
Even oil and gas heaters require a significant amount of electricity to run. The fan for our HVAC uses about 600W while on, which will tax most battery systems pretty quickly, even assuming you still have gas or oil to burn.

Sure, you can use propane heaters or something that require no power at all, but those tend to be unsafe in enclosed areas.

That's the thing, using electric appliances and vehicles means you can actually rely on more than one source of energy (including oil, using generators). A gas heater uses nothing but gas. An electric heat pump can be powered by anything that pushes electrons.
See the last few winters down here in Texas for examples. Electrical failures aren't unlikely

Cold/freezing means heavier lines that may fall and so on

Gas compressors also failed because ERCOT and local utilities were blind with regards to load shedding and critical loads. You must build for total system resilience, and not assume your continuity plans will be robust because of disparate energy sources. Clearly you can’t assume the competence of some system operators.
