bindonce

You can use it anywhere but it'll be especially helpful for long lists. Angular binds anything in double curlies, creating watchers that dirty check and evaluate with every digest cycle. It's tempting (and IMO Angular incorrectly encourages users) to use double curlies for templating everwhere, so in typical list views you can end up with thousands of watchers on data that never needs to change once the page is rendered. This is slow, especially for searching and sorting. Further reading[1] Before this release it's been necessary to write custom directives or use a tool like Bindonce[2] to turn off data binding where it's not needed.

Doesn't https://github.com/Pasvaz/bindonce already handle this?

I would argue there is more than sufficient interest :) All you have to do is scan the angularjs google groups for ngRepeat issues. Infact, one of the solutions proposed for ngRepeat issue (with lot of caveats) has 300+ stars no github https://github.com/Pasvaz/bindonce Including me, there are lot of folks who would find your solution very useful. You are addressing a fundamental O(n) scaling problem in AngularJS.
