I haven't kept up with changes to GCP's load-balancing, and they've introduced a new kind of global L7 load-balancer, and the ones which I am used to are now termed "classic".
I am not able to find ways to create these new style of load-balancers using gcloud CLI. Is there a way to do this?

Create Global HTTPS load-balancer with gcloud
Just to mark the question answered, I will post @John_Hanley's reply here:
Set the flag like this:
gcloud gcloud compute backend-services create --load-balancing-scheme=EXTERNAL_MANAGED
