I've been wondering whether to deprecate "use" tags in rooms and the "define game" block (equivalent in QDK to the "Edit Usable Objects" buttons in the Room Properties and Game Properties windows).

The reason for this is it's a much better idea to define what happens when an object is used in the actual object definition, rather than somewhere else - i.e. all "use" information should be in the object's "use" tags (in QDK, Object Properties > Interactions > Edit 'Use' Details > "Use object (on its own)").

Of course the feature would still be supported for games written in Quest 3.x and earlier, it would just be officially deprecated and not supported by QDK 4.0.

Any thoughts on this?

Seams like a sensible idea, it is much easire if as much of a objects defination/interaction is viewable in one place.

But it would make the ability of having object react differently in different locations slightly more complicated to code.

On balance I would go with your idea

Yes, good idea Alex.

I've certainly never used those commands.
