Perhaps that’s just because no wizard is well-versed in non-euclidean geometry well-enough to understand how it would work in a non-enclosed space.
Could be. Hard to tell without the author telling us.
Besides, enclosed is relative. Maybe light doesn’t travel through it, but neutrinos and your enemy’s spells do.
I think most spells are disrupted by solid objects. And most offensive spells would risk destroying whatever you charmed. Would be interesting to try it on something made of glass, though.
It doesn’t matter. As long as it takes longer to travel through, it works. For example, you could use different kinds of glass to make retroflectors using the same principle, since light will travel at different speeds.
Oh, I see. Cool. I assumed they were purely theoretical.
Perhaps the same spell works. If the same spell could make something two or three times bigger on the inside, then why not one half times bigger?
Interesting point. I doubt it works by specifying the increase as a number, though.
Hmm, there are probably other uses for containers with shrunken insides.

Inflatable mattresses (or waterbeds) that can be filled quickly/efficiently.
If rooms can be enchanted in this way (houses can certainly be bigger on the inside) then enchanting a long hallway in this way would allow people to walk longer distances in a short amount of time.
If the container is transparent, it could be used as a magnifying glass for things you placed inside.

Wizards already have shrinking charms for the first one, but well done.
In a sense they are. I’ve never seen anything about anybody actually doing that. I just know it would work in theory.
Lenses and optic fibers and such work on the same principle, but they aren’t cone points.
