No, I believe this is *precisely *the thing to worry about - these nits and
catch-case gotchas are the sort of things developers see in an emerging
API/polyfill and say "awe, that looks like an fractured, uncertain hassle,
I'll just wait until it is native in all browsers" <-- we must avoid this
at all cost, the web needs this *now*.
