Recursive variables are _always_ expanded recursively.
What you mean is, they're not expanded _when_ you expect them to be.

100% correct.

It's neither a bug nor a documentation flaw--well, anyway, the behavior
_IS_ documented.
See the GNU make manual section "How `make' Reads a Makefile", in the
chapter "Writing Makefiles".
If you have specific suggestions as to where references to this section
could be added to make it simpler to find, please let us know.
Thanks.
