`SpecificInterface` seems oddly placed. It appears to be in ids.h just because it's used by typed_insts.h, but maybe that should be factored differently? We typically aren't having typed_insts.h depend on non-ID types. To that end, I'm splitting it out to its own file so that at least I'm not adding a `ValueStore` dep inside ids.h --------- Co-authored-by: Richard Smith <richard@metafoo.co.uk>
