This is not a correction; you're right. So the sane alternatives are
either continuing to ship a header and tell users
to just import it, or telling users that they're no longer in a simple
"just include/import one file" world and that they now
need to build source files in order to get the library parts. Which is
different from telling them to link to a library.
