Objection to the deletion of F69

Hi WCAG WG,

I learned that after James Nurthen had devised a technique that shows  
failure of content to scale under page zoom, the discussion has now  
concluded that F69 should be simply dropped.

 From an evaluation standpoint, the failures are of critical  
importance since they do not come with the usual disclaimer that  
"failure to conform does not mean that the SC is not met"  - a  
statement that we find under nearly (?) all tests in techniques,  
making them difficult to use in a conclusive evaluation procedure.

So I propose to think twice before deleting failures that provide at  
least *some* measure of assessing conformance to success criteria. I  
can find no argument why the proposed new example for F69
http://jnurthen.users.sonic.net/resize.html

..is unsuitable to demonstrate a failure of supporting page zoom.  It  
'works' in several browsers that I tried it in.

Regards,
Detlev
