The list can be autogenerated, yes, but needs to be reviewed by a human.
Since fc-query only checks codepoint coverage, it misses cases, where
additional truetype features must be present to render a language
correctly. If that happens, the corresponding language tag should be
removed. Also, for CJK fonts the list will include Greek and Cyrillic at
least, but we all know that those fonts are not really suitable for
rendering those languages.
