As a general principle, it tends to happen because people, who often 
haven't read the standards, keep re-inventing things that break 
fundamental design principles.

My guess, in the case of vertical centering, the problem is that it 
breaks incremental rendering.  Breaches are allowed, but most of the 
current ones are in areas that would only be used by experts, who, 
presumably can make a reasoned decision as to whether the effect 
justifies the loss of incremental rendering.  Vertical centering would 
almost certainly result in a large proportion of pages using it and 
therefore break incremental rendering on a large scale.
