Just to clarify: yes, I think we should find a way to move forward with 
this series without an eagerness toggle.

That doesn't imply that we'll be using the capping as proposed here (I 
hate it, it's just tricky to work around it for now).

And ideally, we can do that without any temporary tunables, because I'm 
sure it is a problem we can solve internally long-term.
