To stay true to domain limits, ddrescue could issue a corrected hrdbs rounded read in direct mode, but only use the part that was requested.
This solution could even be automatic, as the only negative effect would be a potentially unnecessary second read of the same block, when the other halve is eventually requested in another run. Yes, it means throwing away successfully read data, but this is generally in the responsibility of a user requesting a non-rounded domain, and no different from what really happens when reading the same domain from a block device without direct mode.
