Given ONLY the playlist-id, can I create a link that starts playing at the first video?
Whenever I try to remove the video-id from a "watch"-url, it breaks, and linking to the "playlist"-endpoint doesn't start playing immediately.
Why does YouTube require a first video-id to be specified?
My reason for not including the video-id is that I want the player to start playing the first video even after the owner modifies the playlist and perhaps remove or replace the first video. I don't want the link to break just because of this.
To be clear this is what I meant:
Works:

Does not work (for me at least):

https://www.youtube.com/watch?list=PL180845BD0BEEE980

Doing the same with an embedded player apparently works fine, but not with a browser a-link.
You mean, for example embed the playlist without specifiyng the video_id, right?
If so, you can try:

or
https://www.youtube.com/embed/?listType=playlist&list=PLMlNiWEoh5QrLU6C7_Ad71UtRpACh3FdQ
And - for autoplay the playlist - you have to add &autoplay=1&mute=0 parameters - after the playlist_id - (it will autoplay the playlist, but, muted).
Otherwise, it wont autoplay.
