cat > foo.el <<EOF
(eval-after-load 'foo
  (message "feature foo loaded: %s" (featurep 'foo)))
EOF

emacs -Q -l foo.el

According to the doc string of eval-after-load:

  Alternatively, FILE can be a feature (i.e. a symbol), in which case FORM
  is evaluated at the end of any file that ‘provide’s this feature.

So I would expect that the above form is not run because the file
foo.el does not provide the feature foo.  Yet the algorithm
underlying eval-after-load compares the symbol foo with the string
"foo.el" and this is sufficient to evaluate the form.

I think that the behavior described in the docstring would be
useful: my init.el is broken into smaller files which have the same
names as the features they refer to.  So I suggest to change the
behavior of eval-after-load instead of fixing its docstring.  But
there might also be other issues that I am not aware of.

You are right, it must have been too early in the morning for me.
I am sorry for the noise.

Closing.
