Ideally a package does increase the so version (the number behind `.so` as listed in e.g. `common/shlibs` in xbps-src).
spdlog did not do that in 1.10.0 ( https://github.com/gabime/spdlog/issues/2369 ), but they changed their build system to also include minor version in there, so this specific issue is unlikely to happen again.

Void currently doesn't have tooling in xbps-src to track symbols, so no automatic way for detecting this.
You (or a script) could in theory just install all of these packages and check if all the symbols do resolve.
