ok, so update is a depreciated alias, so upgrade it is!
Back in the day `yum upgrade` was the equivalent of `yum update --obsoletes`, which means that if a package has been renamed or replaced, you'd get the new version, whereas a plain `yum update` would not replace those packages.
This was rather confusing, and approximately nobody doesn't want Obsoletes to work when updating, so they were later unified to follow the `yum upgrade` behavior, but the `yum update` syntax was kept since that was burned into many peoples' skulls.
dnf is intended to replace yum, and one day in the not too distant future people will be running `yum update` and be none the wiser that it is actually what we now call dnf doing the work. So dnf must inherit all yum's little weird oddities, which means `(yum|dnf) upgrade` and `(yum|dnf) update` will probably do the same thing until on or about the heat death of the universe.
So, there's no need to change your muscle memory if you don't want to. ;-)
