geocode-glib-2.0.pc doesn't get installed?

NEWS says

3.26.3
------

This release adds support for libsoup 3.x. To use the libsoup 3.x build,
applications will need to be adapted to look for the "-2.0" version of the API.
This allows both native and interpreted applications to select which version
of libsoup they want geocode-glib to use as the backend, and for both versions
to be installed in distributions.

but regardless of the setting of -Dsoup2={true,false} geocode-glib just installs geocode-glib-1.0.pc and libgeocode-glib.so.0.0.0.

Any guidance on how to make these parallel installable? Am I supposed to rename and munge the .pc file? Surely not...
