I'd prefer browser makers focus on improving the browser and stack support, and leaving "creative functionality that only a fraction of the users might want" to extension authors. I don't need the already tiny number of folks actually working on a browser to be spread even thinner by also having to become versioned registry maintainers (because you can bet your teeth no one's going to hire additional FTEs for that)
