Ah, I was so fixated on the "pasta" joke, you're right, I missed the other thing! Yeah, I can understand you missing that auto scroll feature.
From what I can tell, it doesn't come as easily as it should natively across all applications, although it appears Firefox has this functionality built in. I found a forum post here from not too long ago. Does this help in your case? :)
And here, some folks are discussing a scripty way to do it system-wide. YMMV it sounds like, and I'm honestly surprised this isn't just a tick-box feature by now.
Then change the keyboard shortcuts of your terminal so that it does that. If you can't, then switch to a terminal that lets you change the keyboard shortcuts.
What Ctrl+Shift+(do a little spin)+Ins isn't intuitive enough for you??
Jokes aside, that's understandable. I guess I've just become used to it, but there must be some way to override the default binding if you don't like it... Personally I like the kitty terminal's approach which uses mod+c/v for copy and paste in the terminal like you'd expect, while still leaving ctrl+c/v for sigint and verbatim respectively.
