Why this idea:

If a new tenant is spinned-off due to WAAP poc request the tenant is completely empty.

The customer than needs first to setup DNS in advance to start with WAAP
services configuration etc. and testing.

I think the dns setup like dns delegation could be automated right away
with an f5 offered/managed demo/testing/poc whatever domain.

Detail:

tenant initialization covers automatically a pre-configured dns delegation.

Example pre-configured auto dns delegation: <tenant-name>.f5demo.com

Value:

This idea would help new customers requesting a PoC immediately
starting with a fresh load balancer setup including a proper FQDN
which refers to the pre-configured dns delegation.

For instance a new service could be created with "www.<tenant-name>.f5demo.com
including auto cert right away without wasting time for the manual dns setup.
