What you're missing is that making the change is trivial.

Getting it deployed is another story.  There are an estimated 2.5 million
or so hosts on the Internet, many of them PC's, Macs, and various
legacy systems dating back to the Stone Age.  Many dont have software
maintenance contracts, or are running release of software no longer supported.

I dont' have kernel source for AIX 2.2.1 - it's going to be a REAL
challenge for me to make the change for my two home systems, which IBM
stopped supporting 5 years ago.
