Summary

Remove the TextTrackList and TextTrackCueList item methods.

Motivation

These have never been in the spec:

https://html.spec.whatwg.org/#texttracklist https://html.spec.whatwg.org/#texttrackcuelist

The support for anonymous indexed property getters was added after the implementation of TextTrackList and TextTrackCueList, so it's no surprise why things are this way.

Compatibility Risk

WebKit also has these, and Edge does too. Gecko does not, nor did Presto.

Given the usage, this scarcely matters.

Alternative implementation suggestion for web developers

Use tracks[i] instead of tracks.item(i)

Usage information from UseCounter

Most days these don't register a single hit, so it's truly tiny usage.

Entry on the feature dashboard

Requesting approval to remove too?

Yes.
