shouldn't these ideally come from a config or a flag so that the market can define it based on the infra they have deployed/tuned?

No. As stated in the Slack thread, these should be fixed and the operator should ensure that their infra can handle these within given deadlines. These haven't yet been specified, but the default deadline of 30s was chosen to be above and beyond what should ever be hit in a functioning system.

These values also need to be documented in the API definition which is inherently not configurable (see AIP-158.
