-1. I disagree.
I am not convinced that requiring names is a good idea. I've asked several times why there is a desire to require names, and I'm not seeing any persuasive arguments that are not already addressed by UUIDs. We have UUID values to allow for acting upon an individual resource. Names are there as a convenience. Requiring names, especially unique names, would make Magnum harder to use for API users driving Magnum from other systems. I want to keep the friction as low as possible.
I'm fine with replacing "None" with an empty string.
Consistency with Nova would be a valid argument if we were being more restrictive, but that's not the case. We are more permissive. You can use Magnum in the same way you use Nova if you want, by adding names to all resources. I don't see the wisdom in forcing that style of use without a technical reason for it.

IMHO, making the Bay/Baymodel name as a MUST will bring more flexibility to end user as Magnum also support operating Bay/Baymodel via names and the name might be more meaningful to end users.
Perhaps we can borrow some iead from nova, the concept in magnum can be mapped to nova as following:
1) instance => bay
2) flavor => baymodel
So I think that a solution might be as following:
1) Make name as a MUST for both bay/baymodel
2) Update magnum client to use following style for bay-create and baymodel-create: DO NOT add "--name" option
root at devstack007:/tmp# nova boot
usage: nova boot [--flavor <flavor>] [--image <image>]
[--image-with <key=value>] [--boot-volume <volume_id>]
[--snapshot <snapshot_id>] [--min-count <number>]
[--max-count <number>] [--meta <key=value>]
[--file <dst-path=src-path>] [--key-name <key-name>]
[--config-drive <value>] [--poll]
error: too few arguments
Try 'nova help boot' for more information.
root at devstack007:/tmp# nova flavor-create
usage: nova flavor-create [--ephemeral <ephemeral>] [--swap <swap>]
[--rxtx-factor <factor>] [--is-public <is-public>]
<name> <id> <ram> <disk> <vcpus>
