I guess the default key is a problem too. Mainly since it might trick developers/manufactures that this somehow makes the key exchange secure if you use it while setting a device unique key.
I do work with OSDP devices and I have heard this argument from manufactures, like "we only support setting a new key while using the default key, it's more secure that way".
While it, at best, will just obfuscate the process.
