It would be a shame to remove this feature, IMO. If that's the case then we'd have to keep a.out alive for alpha, since that's the OSF/1 binary format (at least the only one we support - I'm not sure if later versions of OSF/1 ended up getting ELF). Which I guess we could do, but the question is whether people really do have OSF/1 binaries. It was really useful early on as a source of known-good binaries to test with, but I'm not convinced it's still in use. It's not like there were OSF/1 binaries that we didn't havce access to natively (well, there _were_ special ones that didn't have open source versions, but most of them required more system-side support than Linux ever implemented, afaik).
