Yeah, I noticed some similar funny behavior on Slack's side as well with
respect to the icon url and icon emoji, but I'm worried that if we document it
within the processor, Slack will change the behavior and those docs will be out
of date. I'm also not sure we can anticipate all those idiosyncrasies with
their API, so I guess defeatism has set in from my perspective.
Plus, it sounds like your experience is different than mine. Slack seems to
cache the icon url/emoji on a per-username basis. If I change the username, I
can get different icons/emojis, otherwise they stay the same.
