Devendoring

It would be great to work on some devendoring of "placeholderkv". Distros (I represent Fedora/EPEL in this context) prefer dynamic linking to system libraries instead of vendored packages with included deps.

It would be great to have native support for using system libs for everything possible in the make file, and perhaps some CI pipelines testing various versions, etc. so that it's easier to monitor if/when things break and on what versions so that expectations can be set.
