NetBSD/i386 was the original port of NetBSD, and was initially released as NetBSD 0.8. There were complete sets of binaries made of NetBSD/i386 for every release thereafter. This is going to be true for the foreseeable future.
Currently there isn't a specific port maintainer for NetBSD/i386, so the core group is responsible for it.
