As far as the discussion you're quoting above, no. As I mentioned, 
buildhistory-extra.bbclass isn't intended to go into OE-Core.

At the moment buildhistory isn't exposed in Toaster beyond how it's being used 
to get information on packages and image contents. Independent of the changes 
in the above quoted discussion, you could start exposing buildhistory in 
Toaster, but the problem is you need to choose which build to compare it to, 
or you'll just get the last build which may not make sense in a Toaster 
context.

Cheers,
Paul
