CEDET was promising, I followed it closely around 2007-2011 but it never
delivered, IME. I remember being very frustrated by the inability to set up
a simple "find the definition". Some awkward thing called "senator" had to
be built, I think. Many (re)inventions there, as there were elsewhere (i.e.
SLIME): Emacs simply didn't have the infrastructure of Eldoc, Xref,
Flymake, etc that it does now.

Also it suffers from the problem of not being LSP :) CEDET is an
Emacs-specific protocol and an Emacs-specific toolkit to develop
language-specific tools that speak that protocol. LSP is an editor agnostic
and language agnostic protocol only. A very clever idea. You need
relatively little effort on both sides to get something really useful
going. And any effort you spend on one side is worth n-fold on the other
side. That is its winning formula.
