Dealing with ANY

[slifty]

Task

Description

We have a magical term in our dataType constants: ANY.

Every type bucket is required to have an ANY subtype, which will then map to any type within that bucket. This is all documented, and so folks who are looking to write filters for payloads are expected to account for this.

There are two followup questions:

1. Should the value of this magic term be a constant itself, allowing folks to reference it in their code rather than hard coding the ".ANY"

2. Should we have a root level ANY as well, which would map to literally any payload type.

For example, here is some draft code of a payload filter by type:

filterPayloadsByType = (payloads, type) => payloads.filter(
  (payload) => payload.type.test(
    RegExp(`^${type.replace(/\.ANY$/, '.*')}$`,
  ))

Note: we dropped the use of RegExp in here for speed and safety reasons, and used startsWith instead.
