FRR is used in production and isn't academic, I don't know where you got that impression. Microsoft runs FRR on SONiC. Vyos runs FRR. 6wind runs FRR. Cumulus Networks runs FRR. Juniper runs FRR in certain products. VMware runs FRR. Broadcom is integrating it. I don't think you are very familiar with the scope of changes that have gone in since Quagga. Not to detract from BIRD - which is a great, solid BGP implementation - but it is disingenuous to say FRR isn't used in production.
