It's pretty simple: bitcoin-dev is read by hundreds of people. This has nothing
to do with authority. It's about not wasting the time of those people.

OpenTimestamps is, as the name suggests, for cryptographic timestamping. As is
obvious to anyone with a good knowledge of cryptography, a cryptographic
timestamp proves that data existed prior to some point in time. That's it.

The fact you keep bringing up linearization for a timestmaping service makes me
think something is missing in your understanding of cryptography. Tell me, how
exactly do you think linearization would help in an example use-case? More
specifically, what attack would be prevented?
