Is fast charging just standard these days? Does anyone disable it?

Yes but fast charging reduces the life of the battery faster than normal charging due to the increased heat. Google it or call Samsung. No it doesn't harm the battery but will reduce its life quicker

Please post a credible source for this information.

From my understanding, the reason the charge slows down as it gets full is to make sure it doesn’t get overcharged or explode. The way the Tesla employees explained it to about the super chargers is “if you have an empty glass, you can pour water into it fairly quickly without spilling, but as the glass gets full you have to slow down to fill it to the top without making a mess”

Also, I seem to remember Samsung saying something about how after a year the Note 8 should still have over 90% battery capacity. They said this because every was worried about the exploding batteries.

There are charging algorithms that govern the charging of batteries. The specific standard or algorithm is based on the chemistry of the battery.
