Maybe this should have been discussed in 2009, when I implemented the "message" type for items.
KoL has a bunch of things which give you a cute "message" when you use them but otherwise have no particular effect. wind chimes, for example. I figured if you troubled to use them, you'd want to see the message.
For that matter, I also set up to show you the message when you grow a familiar, since that is also cute - and it is literally something you get to see exactly once per familiar. Somebody decided that was "annoying", so that was commented out. That means that every time I use a new familiar, these days, I go to the Relay Browser and do it manually, so I can see the "once ever per familiar" message.
This is a "fun" feature, not a "serious" feature.
Apparently, KoLmafia is only for "serious" things, these days.
This PR caught my eye, because there is an open PR which, among much bigger things, marks all the "mixed drink with a fly in it" items as "message". If you try to drink one, KoL fails and tells you that you change your mind. I.e., it gives you a cute message.
We don't actually support that, yet. I'm thinking we should, but now I see that if we do, we're probably just setting ourselves up for bug reports from the humorless. Which is strange, since "humor" is SUPPOSED to be one of the things that people like about KoL.
