It's not docsis. It's the coax/network of the provider. In a way, your hate for docsis itself is like someone hating General Motors because they had a bad experience with a dealer over car repairs. The car itself might not have been that crappy had the dealer done their job and fixed it right the first time, but if you go to another market area, everything is fine. But you end up hatting the car because the dealer sucked. I have DOCSIS 3.1 where I live. It's reliable and works just fine and is why i'm a "if it's not broke, don't touch it" kinda customer. I'm fine with coax and I really do a lot of media crap. I've NEVER EVER sit here and said, "Gee, I wish I had fiber". Better yet, I've never wished for a sat phone when I drop a call on my cell because I think cell phone service sucks and sat phones are the way to go. If your provider would get it's poo together, you would be having a better experience. If you had Verizon, you can get their home broadband (wireless) for $25. But maybe sooner then later, you will get your glass wire.
