Is there any existing standardized middle ground between UUIDs, random bits of length n, and serial IDs? I totally buy that UUIDs are unpleasant in URLs in many cases. I can also imagine that in many cases UUIDs for small objects might be a huge % of on the wire payload size. But besides human friendly slugs, which usually have an ID mapping behind the scenes in my experience, it seems like there might be more work than value for startups in many cases.
