A drawback is that this option also prevents any usage of SSE on the i586 platform.
That could be a pretty severe drawback.
For example, I’ve been working on some GC performance optimizations that can take advantage of SSE when available. I think this change would mean that the relevant code would require compile-time disable and could not use a runtime configuration test (which would succeed and permit SSE usage on anything other than low end embedded or very ancient hardware).
