I think I did misunderstand you somewhat, Michael.

What the scheme should be used for is that all those different .grfs would use the same cargo-IDs and bit flags to ensure compatibility.
That does explain it a lot. I assumed that this was what you were going to work towards with newcargo[w].grf but not with much choice about what you play or don't play. If it is intended that we have quite a bit of choice (with sensible and playable defaults, of course, to keep it simple for people who don't want to fiddle) then I would personally be quite happy with your scheme.

This is the only real problem that I have - I think it could get restrictive for specialised GRFs if the use of these standard cargos is unknown or highly variable. However, I find it difficult to see other GRFs using more than a few slots without overwriting the entire set of cargos because the game would again become too crowded and because the structure would become too complicated - so the free slots allocated might actually be enough in the end.

Apart from what I've written above, yes, I would agree with your scheme.

I don't really agree here - if we agree on this as a "standard" then you can of course overwrite/disable the cargos with a regional set if you want to. I feel that this would be the best solution for everyone - and remember that it is only for temperate climate.
