Compared to consistency with the header files? I guess either way there's a chance of mismatch. (would it be really bad to do header search but using the library name? having the metadata in the header search path, but based on library name (solving the config-per-module V config-per-library) - I guess that's a more novel search, rather than something closer to an existing search process/path/etc (but it's not like we can actually use the linker search path resolution, can we? - the linker doesn't generally report the paths it actually found in a machine readable way that the build system could then just swap the extension on and check for existence), but would allow the metadata to be more portable/have relative paths to headers)
