Comment (by peterwilsoncc):

 It might be worth changing how the ETAG header is generated, not to hide
 the WordPress version but in order to better calculate a value that
 changes with the scripts' versions rather than the WordPress version.

 As is, a 304 HTTP response may be returned despite the scripts' version
 changing. I've attached a POC to demonstrate a more accurate response.
 This helps explain some caching issues I've had working on WordPress-
 Develop.

 While the POC does hide the WP version behind a hash, it won't help hide
 the WordPress version from any bots as the ETAG header would continue to
 provide a method for bots to determine the current version of WP if they
 store the hashes.
