Sorry y'all I'm not going to make it today. At daughter's school for parent teacher conference and running late.
Updates: @David Haig has been making good strides and might have an initial PR soon. I'm just wondering about expanding the scope of #65409 to have a crack at improving the borrowing hints - keen on whether people are ok with that direction or if they've got other suggestions, but that can all be done offline (or should I say async?).
