It's more than a waste of resources:  it's pathologically broken and
Cisco decline to fix it, despite the fact that enabling ingress-only or
egress-only is fully supported via API in the Broadcom SDKs, and
consequently the amount of configuration glue required to fix it in
NX-OS is nearly zero.

Broadcom chipsets don't support netflow, so sflow is the only game in
town if you need data telemetry on broadcom-based ToR boxes.

As I said in a previous email on this thread, refusing to support this
properly is a harmful and short sighted approach to customers' requirements.
