I imagine these potential performance issues would also be exacerbated 
by editing over TRAMP. Currently, the latest development builds of Eglot 
work nicely with TRAMP files, but having to send fontification results 
back to the local Emacs instance could be a problem over slow connections.

Having something built into Emacs (as much as possible) would also have 
the benefit of allowing users to read a properly-fontified source file 
even for languages they haven't installed tools for. For example, I 
might want to read a C# source file occasionally, despite not having a 
C# compiler/LSP server.
