Well in reality it seems to work just fine for me when I try. Can you
substantiate better why it wouldn't be possible?

Why do you say that metadata are controls? Metadata are some state in
the input item, that get successively updated at many various layers
already.

It fundamentally does not work in this one particular implementation
approach that writes an M3U playlist. Let's keep in mind that youtube-dl
is the one really extracting the metadata. If the ytdl access processes
directly itself its youtube-dl output - which makes sense - it works, in
a sensible way.
