Unfortunately only the very top-of-the-line (very expensive) variable speed compressor units are rated for anything close to 24 SEER / -5F (unless that's what you meant by modern systems).
When I researched this year on replacing my A/C / Propane Furnace system with a heat pump, I found that companies didn't seem to want to advertise what temperatures their heat pumps can operate effectively at. If I look at some marketing materials from Google it seems companies like Carrier and Trane are only willing to talk about their heat pumps working in low temperatures if it's regarding their top-of-the-line (very expensive) variable speed compressor units. No one talks about what temps the mid range units can handle, and I'm guessing it's because they don't work well below 20F.
If everyone uses resistive heat during that 1% of the time that it's -20F or below, the electric grid goes down and then no one gets heat. Consider what just happened in the southeast with TVA and rolling blackouts. That was precisely because it was too cold for heat pumps and so everyone's resistive heat engaged at the same time. I don't think your EV range comparison is a particularly good one. You can control your stops on a road trip, you can't control when it's colder than -20F outside.
The lack of an NSFW content filter is mind-boggling. They have offered an "NSFW" checkbox when uploading avatars for years, but still to this day have given users no way to filter out avatars tagged "NSFW" in game. They could solve most of this problem fairly easily by blocking users from wearing avatars tagged "NSFW" in public instances. NSFW content doesn't belong in public instances and indeed it's a bannable offense already - so why they have not made this a priority is a mystery. Guess the developers are too focused on implementing EAC.
The crashers in public lobbies are real problems, but you should be aware that the vast majority of malicious behavior is not coming from modified clients. It's coming from avatars with specifically programmed shaders which causes others' clients to crash, or purposely malformed package files that cause the client to crash, or sound sources that cause the client to crash. All of those methods to maliciously crash other users are uploaded with VRchat's own SDK in Unity and requires zero 3rd party mods. On the flip side, there were mods specifically designed to prevent crashes by these malicious avatars that can no longer be used due to EAC (FinalIKSanitizer, TrueShaderAntiCrash, etc).
