That's fine.  My surmise, based on report rates for other problems we've 
had in nightly builds in the last 8 years or so, is that 2 bugs reported 
within a day of the problem being introduced means that pages that 
trigger the problem are not particularly rare.  But it could just be 
chance too.

As I said in my initial mail, this was just a data point that you might 
want to consider.  Or might want to not consider.  I don't actually care 
that much whether you do or not.

Honestly, the open web isn't all we need to be concerned with.  It's 
just easier to analyze, and should be the first priority if there's a 
conflict.  That doesn't mean other things don't matter.

I should have been clearer: this is a deduction based on the speed with 
which the bugs were reported.

Pretty much, yes.  I will certainly be doing so as a UA developer. 
Whether you choose to assume so or not is up to you.
