We, Chromium project, would like to change -webkit-appearance CSS property behavior so that it follows the current css-ui-4 draft [1], and I'd like to know your opinions about the changes. Do you support each of the following changes?

1) Add support of 'auto' keyword

2) Unship keywords which are not necessary for web compatibility

  Low usage keywords such as 'inner-spin-button'.  This doesn't mean we'll remove painting code for such keywords. 'auto' keyword will be used instead.

3) Ship unprefixed 'appearance' property
