Sorry, I don't understand these changes--can you walk me through them tomorrow?

[schloerke]

Will do!

I suggest adding a prepend = TRUE argument to pr$mount() and then not having to pass pr_private

I don't think you want to do this unmount...? With #883, you'll be able to mount two subrouters to one path and have one fall through to the other.

[schloerke]

I'll be sure to address that in the PR. There's a lot of decisions to be made in #883

For now, I'd like to keep existing behavior where it was overwritten.

• Bullet point added in description of Mounted router fall back to parent router when route is not found #883

[jcheng5]

And if you still do want to unmount, I think you would then need to factor in how it affects the after index if it's a non-NULL, non-zero value.

[schloerke]

Hmmmm. Let's keep this in draft to see if we're even going to merge #883
