Is there a way to mark all notifications as "read" in 10.x? If not, I'd like to request one. Sure, I can probably write a plugin and modify the widget appropriately, but I'd rather it be part of the product OOTB.

Hi Robert Miller,
You can mark all notifications read by category which helps a lot. Not from your screen capture but from the notifications Icon in the top menu. Simply click the lightning bolt icon
In the drop-down box, you will see Unread notifications, a list of them, View All and Settings.
on the right of each title banner of each category hover over to see a checkmark, click that for those notifications. do that for each grey heading.
You will see a checkmark and an x for each individual item
Hope this helps :)
This works for each of the 5 Categories, so I would expect to click 5 times at a minimum to clear all content if I had a notification in each of the following: For your review, responses to you, responses to discussions you participated in, subscriptions, status updates. I could end up clicking more than 5 times if I decided to do each item under each category. This feature is definitely better than 99 clicks on 99 single notifications under view all for sure!
