Well, I think we can agree that it's not an urgent need, and we can probably agree on a handful of other things that ought to be higher in priority. But, I think this is a foundational responsibility of the witnesses -- at least for the top-20 witnesses. This is what the blockchain pays them for. IMO, in an ideal world the top-20 witnesses would:

1. Run a witness node & seed node.
2. Run a public API with a fairly complete set of plugins.
3. Understand the impact of all dynamic parameters that they control, and communicate to stakeholders with the reasons why they set the parameters the way they do.

If that parameter is set to zero simply because, "It has (almost) always been done that way", then a better understanding is needed. If there's a reason to leave it at zero, fine. But it shouldn't be pegged there just because no one thought about it.
