Why not?
Because it's an undocumented binary diff format with sequence information
compressed in a MediaWiki-specific way, which is packed into an array and
then serialized using PHP's undocumented serialization format, then
compressed with zlib using undocumented parameters, then stored in a
MediaWiki-specific object, then serialized again. It's not a process
that's interchange-friendly.
