Why do non-closed captioned subtitles no longer exist as an option on streaming?

When DVDs came out, many offered both closed captions and subtitles as an option. In fact people would complain if subtitles weren't included. You see, subtitles don't include words indicating sound effects, noises, or music and are much less intrusive than closed captions which are designed for people who are hard of hearing. However from what I can tell subtitles outside of foreign titles no longer exist. It seems like this would be such an easy thing to facilitate with current technology. Is there a reason for it?
