That's your choice. You are entitled to make it.

...Contains many errors. One day I'll get round to publishing a rebuttal
page, because I'm rather tired of seeing this touted as "fact" so often.

That's your opinion. It is not everyone's. Many people consider SRS to be
a workable system; whether or not the entire world moves over to SRS
doesn't really matter. It's a common misconception that SPF/SRS requires
100% participation to work, but that's just wrong. SPF/SRS becomes more
effective as more people use it, but it is *already* effective (and
certahnily effective enough for me) despite the fact that you've decided
not to support it.
