Do you mean the outdated rust-simplicity version?

This one: https://crates.io/crates/simplicityhl

I don't understand. Why would the LSP care about what's on crates.io?

This is the SimplicityHL repo. By definition it's the most up-to-date version of SimplicityHL.

The main reasoning behind this is having the Simplicity LSP on crates.io

If it is there, instead of having three commands (git clone, cd, cargo install), you will have only one install command (better dev experience)

Simplicity LSP cannot be published to crates.io with a dependency that looks like this:

simplicityhl = { git = "https://github.com/BlockstreamResearch/SimplicityHL.git", rev = "e68e1c6" }

It must have a version tag

Ah, I understand, it's a draft until we can get it into a publishable state.
