This is needed to allow ORDER BY, DISTINCT, etc to work as expected for pg_lsn values. We had previously decided to put this off for 9.5, but in view of commit eeca4cd35e284c72b2ea1b4494e64e7738896e81 there's no reason to avoid a catversion bump for 9.4beta2, and this does make a pretty significant usability difference for pg_lsn.
