For me and you, since we have spent time reading up on with tree sitter
and are familiar with the technologies it makes use of.  But it is by no
means obvious.

I should clarify that these are the users I am concerned with, and
without a reason to, I do not distinguish from "regular" users.

My main worry with these changes, along with the popularity of LSP is
that while they are technological improvements, they all happen at the
deterioration of Emacs' introspectability, increasing the effort it
takes for the user to make changes.  IIUC you can't reload a .el file or
just a singular expression if you want to change how completion via
Eglot or how imenu works via Tree Sitter.  A simple hack becomes a
weekend project.  This is not an unconditional good.
