> ... but changing connector just because it's old is unwise

Well not because it's old, I'm a huge fan of my 1/8" headphone jack.

Type C is intentionally significantly more functional (not to mention the ergonomics of reversibility) but also fully backwards-compatible requiring only passive routing to get you a Type A adapter.

> The issue of type C is that it's trying to accommodate the entire spectrum of applications from very high bandwidth to very low cost.

That's up to the host. You can support just USB 2.0 with the same signals routed as a vanilla type A connector.

There's even super cheap USB-C receptacles that only have the relevant USB 2.0 pins routed out. Like this one [1].

There's really no reason I can think of not to use one.

I've implemented USB-C with PD and SS speeds before, so I know. I've even used if not that exact same connector, but at least a functionally same one from LCSC.

It's just that these reasons seem so inconsequential to me. There's stuff like type C needing two extra resistors even for USB 2.0. Being able to adapt between connectors is also BS in my opinion because you can convert anything between anything if you really wanted to. And if you only use USB HS speeds, you'll just waste connect lifetime of your expensive higher-specced cable. Sure, you can get 2.0 only type C cables, but why? I think there's no good reason to use USB-C besides high bandwidth purposes. Barrel jacks or supply power better. All our normal peripheral devices aren't consuming exponentially more bandwidth anytime soon.
