Using the configuration to get the clojure-lsp version can be misleading if the user set a binary to be used with a custom path. https://calva.io/clojure-lsp/#using-a-custom-clojure-lsp-native-binary

The server info command is really the one source of truth for the clojure-lsp version. I do see you're saying "this is the version configured," so that would sort of be true, but not necessarily the version being used.

The same goes for nrepl. Depending on their classpath and tooling used (lein vs tools.deps), I think a different version of nrepl could be used than the one configured in jack-in deps. We'd also need to be aware of whether they connected to a repl without using jack-in, because in that case the nrepl version could be different too.
