I heavily use eval-after-load in my .emacs.
It seems to me that when there is a need to use eval-after-load in a
package included in Emacs some bad-design is happening. For example,
imenu probably needs to provide a better interface for other packages to
interact with it. What org is doing, in this case, is using
eval-after-load to workaround it. Anyway I am not sure, maybe RMS or the
maintainer could clarify on the use of eval-after-load.
Best,
Leo
