We deliberately decided not to make it a defcustom, and not to provide
any non-trivial default value, so as to avoid the impression that we
as a project want to be responsible for the language grammars, their
correctness, up-to-date sites, and their licenses.  It should be
entirely up to the user and/or the Emacs distros.

However, I think we decided to make it so that each installation
should update the value of the variable with the data of the grammar
just installed.  I see that we don't actually do that -- Yuan, am I
misremembering this?  If not, would you please add code to add to the
variable's value the data of every grammar that is installed?
