My mind head would expect the list to keep scrolling but it just wouldn't without any physical metaphor for why it wouldn't.

What? If I'm sliding physical objects around, I normally expect them to just stop abruptly if they hit something.

...and indeed, that's what scrolling in UIs also did for a very long time, accompanied by a very clear indication in the scrollbar that you've reached the end:

The "designers" happened, and all of a sudden scrollbars turned into these horribly thin and imprecise roundish blobs that are far worse for indicating where exactly you are, and in particular, whether you've reached the end.

I have yet to see something physical that doesn't need to somehow dissipate its energy to come to a halt. If it's rigid and the hurdle is rigid it brakes, bounces back or damages the hurdle. If it's soft it bounces back or squeezes (stretches) and if the hurdle is soft it bounces back or overshoots.

Ever snapped magnets together where one was attached to something much heavier?

and frankly, any personal opinion doesn't matter in this case - it's a non issue. Just give us options to customize it to our preferences, and don't try to force others to follow The One True Way.

ideal scrolling 'hard brake' physics are copper block magnet drop[1], computed in modern devices on the GPU using the spinach NMR library[2]
