The points of standards is that they solve one or more problems for many constituents well enough so that all adopters gain in things like supply chain, design ease, and interoperability. They are rarely going to be optimal for every specific use case. They also often derive from specific designs by a specific company

Adding a standards body into the mix is going to add complexity to the process by definition, but shouldn't be taken as a default "bad", since there are tangible benefits to non-corporation-managed standards. Otherwise they wouldn't exist.
