Yes, this was needed in the initial version, but it is no longer required.
I just sent a patch.

Well.. because scalar registers are limited, the direct unrolling will be
like this for now. We can handle different lengths separately in the future

Since len < 64, the registers are sufficient, so it can be
directly unrolled (a4 is even).
Another benefit of unrolling is that it reduces one load operation
vertically compared to horizontally.
