 There exists a filter
 (https://core.trac.wordpress.org/ticket/18280#comment:5) to allow
 core/plugins to choose to skip certain postmeta in exports.  It would be
 handy to have the same functionality for commentmeta.

 Example implementation: Akismet is already set up to use this filter (as
 implemented in WordPress.com's exporter, which is discussed in #22435) to
 exclude comment meta values from exports that won't be of any utility
 after an import. (https://plugins.trac.wordpress.org/changeset/943192)

 Patch attached.
