WOFF2 and 'meta' table

Apple defines ‘meta’ table that is still outside of OpenType spec. It contains information about languages font supports and designed for. We in Windows 10 decided to add this table to our system fonts and are in process of doing so.

I noticed that this table is not in the list of known table tags (http://www.w3.org/TR/WOFF2/#table_dir_format) and this may be the only real world table that is not compressed by this mechanism. Can we consider adding this table to the list? I know that list is currently full, but maybe we can replace some rarely used table with it?

Thanks,
Sergey
