To be honest I do not understand the idea of such reasoning.

Say if in HTML5 we will decide to always parse <caption>
as such a <span> element: 

  <caption>Caption text</caption> 

will be parsed and create DOM of this structure
  <caption style="display:inline">Caption text</caption> 

Currently HTML parsers create just this for some reason:
  Caption text

These two cases are undistinguishable for the human - so the 
solution is backward compatible. I don't think we can
find existing markup on the web that relies on the fact that <caption>
and </caption> tags are silently ignored by modern browsers.
