The easiest for now would be (3), the coolest, most difficult and probably most dangerous one would be (2). Something like AC_CONFIG_FILES_COMMANDS(some/Makefile, more-user-commands, [more-init-cmds])but then the order of issuing this and the respective AC_CONFIG_FILES(some/Makefile) would be significant. I don't see any way to avoid this.
You could specify that AC_CONFIG_FILES comes first, and *_COMMANDS occurrences come later in the order that appears in the source (and do nothing unless the corresponding AC_CONFIG_FILES exists).
The simplest implementation would amount to two m4_append (actually one m4_append plus one _AC_CONFIG_COMMANDS_INIT) in AC_CONFIG_FILES_COMMANDS, and an m4_ifdef in _AC_CONFIG_REGISTER_DEST.
