Comment (by lancewillett):

 I prefer {{{has-post-thumbnail}}} as it's more explicit (versus a class
 value saying this theme (or current view) supports post-thumbnails in
 general.

 Also looking at back-compat, it's already in use in 2 default themes and
 24 other themes active on WP.org.

 {{{post-thumbnail}}} would be my second choice, but it's already in heavy
 use across many themes, so could be a support headache for theme
 developers. I found 149 themes using it in WP.org and 20 on WP.com.
