Comment (by krogsgard):

 @obenland I agree, that's why I think it should be an optional parameter,
 to be set by the theme developer.

 From my original notes:
         Justification: There are times in building out a theme where you'd
 want the exact featured image or none at all (like a big wide header
 banner or something), but other times it's great to have any 'ole
 fallback, like a more traditional square thumbnail on blog archives.

 There could still be an issue of sandwiching if someone switching themes
 that handle things differently, but that's part of any theme switch --
 some maintenance. Also, for instances where the featured image is called
 with an excerpt or something, I'd imagine most folks would want a default
 featured image from content vs nothing.

 I've found that many people just don't fully grasp the featured image.
 Additionally, for ''really'' old content, setting featured images on a
 bunch of old posts is a pain.

 I won't claim to have the perfect solution, but I think putting some
 functionality in here somewhere would end up being a very well accepted
 feature, if done responsibly.
