Ah, the other direction!

When I ran my first experiments with __gc, I had encapsulated my
userdatum in a table so that I could attach other fields from Lua. I was
surprised when the C objects were not collected (the metatable was
attached to the table, not the userdatum). Then I read the fine print,
so I removed the table and used the userdatum directly.

I'm sure many would love to have this feature.
