You mean if kinds were strings instead of numbers? Yeah, maybe, but essentially it would be the same thing (just from the name you can't get all the context regardless, like the schema, the ecosystem around it, the expected UXetc) and even if what you cite is a minor advantage there are also minor disadvantages (more bytes used, slower to parse, people still have to check some registry to see if they're typing the correct strings, names don't really correspond to anything so one would still have to check guides, names can actually give people the illusion that they understood or can be deceiving etc).
