This doesn't make any sense to me.

foo-objs and foo-y are treated equivalent by the build system, and not
related to modular builds at all.  In fact -y is preffered these days
as it allows to build parts of the multi-object module conditionally using
expressions like:

  foo-y                 += foo_main.o
  foo-$(CONFIG_FOO_BAR) += foo_bar.o
