It is not so much harm, but just that it is easier for a the maintainers
of a major mode to evaluate and perhaps change anything related to the
LSP server configuration, than if they have to make the change in some
other project (in this case emacs.git).  I'd also guess that people
maintaining a specific major mode have more experience and are better at
testing edge-cases specific to a language{,server} than the average
Emacs developer.
