In PyNWB, consider allowing the user to pass all devicemodel arguments to device constructor which creates a devicemodel behind the scenes with the same name + " Model" and links to it.

Lgtm. @oruebel what do you think?

Just some minor enhancements to the changelog, otherwise this looks good. What is the plan for supporting this in PyNWB.

Since the intent seems to be that folks will create extensions of DeviceModel, I'm wondering whether that approach may cause confusion. I'm wondering whether it may be simpler to have some factory method instead, e.g., create_device on NWBFile that would create both the Device and DeviceModel

That makes sense. But factory methods will not work for extensions either if they require additional fields, so users would still have to create the DeviceModelExtension and DeviceExtension manually.

The base branch was changed.
