Since metadata is only needed when building things, but the DLL is needed at runtime, it would be better if the metadata was moved to the LIB import library instead since that is only needed when building things as well. This would save significantly on space when distributing a binary with DLLs.

Arguably, the same could be said about dylibs on all platforms.

Can we close this now that we've got cdylibs?

The problem still exists for regular dylibs though. It's just not as important of a problem anymore.
