That's why it is not removed and left as is.

> The iOS port and multiple third party apps depend on a playlist implemented by the media list player as exposed through VLCKit. You might argue that you could implement a playlist in the VLCKit layer which is partially correct. However, the main scenario is to open playlist files (as in m3u or xspf) with large number of (live) stream URLs and switch between those. This is easily possible with the list player as it uses libvlc’s internal playlist parsers. Removing the list player would require re-implementing a playlist parser in the client app, which is a waste of resources and time.

For reasons I never investigated, the list player was a lot faster at switching channels than stoping, setting a different media and starting a single player instance.

The plan is to write a new libvlc playlist API matching the core
playlist API.
