I have to wholeheartedly agree with your parent here.
The whole purpose of playlists is to organise songs, and almost the entire usecase for removing a song from a playlist is to remove the currently playing song. I almost never want to remove a song under any other circumstances.
This shouldn’t be a power feature, but Spotify makes it unnecessarily difficult to do on the fly.
You're making a few big leaps here. First that self-built playlists are an important feature for users, that people are actively managing their playlists, and that people curate while listening.
Those might all be true for the majority of users, or it might be that you're an outlier. The only way to know is to actually sample real world users.
