Recently Philip rightly noticed that 'major-mode-remap-alist'
would be sufficient.  And indeed, such a command could be implemented
just as

  (defun treesit-add-enabled-mode (non-ts-mode ts-mode)
    (setopt major-mode-remap-alist
            (cons (cons non-ts-mode ts-mode)
                  major-mode-remap-alist)))

Or the idea was to simplify this by using only ts-mode here
while maintaining a huge database of non-ts → ts mappings
in an internal variable?  (that will eventually grow
into something like 'eglot-server-programs')
