> ... 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.
