My apologies, you are of course right. I do this sort of stuff in 
a use-package declaration in the :config section, which is 
executed after the package is loaded, so I tend to forget about 
eval-after-load.

Really? I mean, true, I see it a lot in (mostly older) config 
snippets Google spits up, but I thought it was generally 
discouraged to use a hook if there's no need for it, because it's 
not always as harmless as this example. (In fact, I've run into 
problems with it myself from time to time.)
