Is the loss_timer_updated event sufficient?

[LPardue]

We've had the following todo's for loss_timer_updated in the quic schema for a while, pulling them out into this issue

1. TODO: how about CC algo's that use multiple timers? How generic do these events
   need to be? Just support QUIC-style recovery from the spec or broader?

2. TODO: read up on the loss detection logic in draft-27 onward and see if this suffices

[LPardue]

I'm guessing we are looking for volunteers to help us here. We can ask. In the absence of someone offering it, we can use the WGLC as an indicator that there is consensus on what is already in the draft as sufficient.
