NVM, it's the new default value for "scrolloff":
https://stackoverflow.com/questions/56234414/vim-why-shifth-and-shiftl-not-jumping-on-the-first-and-last-line-on-the-scree
(funny how Google returns that on the first page only *after* one has
figured out they need to include "scrolloff" in their search terms :)

At this point I don't care if it was the fedora packagers or vim
upstream that started it... It's just somewhat funny it took me a year
or two to really notice, and figure that it annoys me enough to bother
getting to the bottom of it...

Now, on to the difficult decision of whether I should grumpily set
it back to 0 in my .vimrc, or continue to put up with it because it
"makes some sort of weird ergonomic sense"... :)
