It isn't an immediate problem, so we can delay it for later.
However, I do worry about the ability to update this in some
non-manual way. Take for example the way we update our character
databases when Unicode adds more characters/scripts: we use the data
files distributed by the Unicode Consortium and process them with
scripts in admin/unidata to produce intermediate files in a format
convenient for processing by Emacs, then we process those intermediate
files as part of building Emacs. Unicode files change maybe or twice
a year, but still, doing all those changes manually would be a burden.
