IESG, authors,

1. Safe?

My main concern is with applicability. In particular, the sentence in section 7 on Deployment 
Status: "We believe it to be a safe default and encourage people running Linux to turn it on: 
...". and a similar sentiment repeated in the conclusions. "and we believe it to be safe 
to turn on by default, as has already happened in a number of Linux distributions."

At the risk of incurring further wrath, and noting that the IESG did request "final comments 
on this action" (hence all the CCs), I think there's something to Bob's observation about the 
word "safe".

What about:

Section 1: "...and we believe it to be safe to turn on by default, ..." -> "...and 
we believe it to be significantly beneficial to turn on by default, ..."
Section 7: "We believe it to be a safe default and ..." -> "We believe it to be a 
significantly beneficial default and ..."

(Yes, this is going to be an Experimental RFC. And yes, turning on FQ_CoDel generally 
results in awesome improvements wrt pfifo. But the two instances of "safe" in 
draft-ietf-aqm-fq-codel-05.txt do imply to me a wider degree of applicability than is 
probably warranted at this juncture. I just hadn't noticed until Bob mentioned it.)
