This is literally what certain manufacturers do. Here’s a side by side of the receiver remote for my setup and the one for the TV (which has never even been connected to the internet). One has these dedicated buttons. The other just has ones labeled for streaming or similar.>!!<

I’ll add that the location of the buttons makes a significant difference. If they’re easy to hit by accident you’re more likely to have grandma launch a service she didn’t mean to and not know how to back out of it. This causes more problems than it solves.
