This makes a large difference :)

Could we enable it by default?

Patch v2 documents the mechanism of increased IO throughput, and
adds a warning about the risk of undetected file collisions:

Since the merge-wait FEATURES setting add for bug 663324 and enabled by default, you'll have to disable merge-wait for parallel-install to be effective with portage-3.0.62. With a few changes it's possible to uncouple them, allowing a batch of queued merges to be installed in parallel.
