[webkit-dev] Unprefixing Blob.webkitSlice() ?

[Darin Fisher]

Happy to see us support unprefixed too.  With other vendors on board, it
seems like a straightforward addition to the platform.

I'm not sure if you are proposing to also remove the prefixed form.  I'm
not sure what it would take to remove the prefixed version.  We'd need some
way to know when it is safe to remove it.  We could surely instrument the
code to measure its use relative to the unprefixed form once it is widely
deployed.
