var vs. let in the same language is a consequence of designing the language by committee, requiring 100% backwards-compatibility, and forbidding the addition of new modes (which is a back-door way to introduce breaking changes, while requiring browser vendors to essentially support multiple versions).

That behaviour is not exclusive to standards committees. The government and private companies do it all the time.

"governments and private companies" certainly do not preclude committees. Quite to the contrary, in fact.
