Ok.  That's what I guessed.

We'll have to see how it looks one day when we have DWARF compaction.
But yeah, it's big and seems impractical for the foreseeable future.
Especially when in most cases the macro source is already in kernel-devel
headers that we already have on hand without any debuginfo at all.
