Ummm... what, exactly is missing?
Read them again.
"Bold font option now includes the keyboard, calculator an dmany icon glyphs"
That does NOT imply that there is a separate setting for the keyboard. It means that when you choose the bold font option, those items will be affected where they were not before.
Likewise the next point: "Reduce motion option now includes Weather, Messages, and multitasking UI animations."
That means they are affected when you choose that option. Not that they get their own options.
There is absolutely NOTHING there about a "dark keyboard" option.
