Great Idea for Useless Fish

[ItMe]

I think the problem is with the way recipes work. It doesn't need seem to be geared for "insert any one of a range of items here" or maybe we'd have more flexibility in other recipes too.

That's true.
And especially as they semi-regularly cull items they dont need to worry too much about item bloat with recipies.
Fishing may be the thing where they have to start taking a look at it though, though I agree with you that this may not be the solution we see.
