The thing is, they spent those years building out the voice assistant support. That was probably a better use of their time than reworking the entire interface to work with a TV remote, in my opinion.

They are a small team with a lot of help from the community. You can't tell the community what to do since they volunteer their time, and the small team has a focused road map that I think makes sense.

I bet you could find another 100 examples of things not done for 5 years, it's just this is the one you in particular want.

In the same 5 years, you could've easily learned how to program, and do it yourself. As a software engineer, I'd say most people can learn to code fairly quickly, so it'd be more like 5 weeks, if that...

Dashboards can get quite complicated and funnily enough TV remotes are not all the same. With a small userbase (it is by far not the most requested feature) it will be hard to maintain such a feature without just fulfilling a one-user-usecase.
