Even then it won't add a significant overhead (that's a tight loop
with ~128 iterations, with likely everything in cache).

But I won't stop you from trying to improve this, if you can justify a
separate index with some great performance numbers, then I'll accept
that.  I just think it's unlikely to be the case.
