I actually think Discovery is doing a reasonably good job of making it feel like it could plausibly be set in that era. Sure, the sets look different, but that's 50 years of set design for you, but things like having the same consoles as in TOS with added holographic display make it feel more to me like an updated look rather than a completely changed one.
I think any potential changes in style are worth having just for the ability to explore the Star Trek universe of that era some more, it's far less fleshed out on screen than I'd like. Like the Klingons just being dudes with facial hair in TOS, the ships always looked like that, there just wasn't the budget.
...or we could go back to buttons and have some sort of throwaway joke about them to explain it away, but that's getting dangerously close to Red Dwarf's "why they still use VHS tapes in the future" joke
