See section 7 of the Fonts spec, entitled "Font Feature Resolution".

http://www.w3.org/TR/css3-fonts/#font-feature-resolution

This section specifies exactly how different property values affect the
final resolved feature settings passed through to the shaping engine.
They do not, and should not, affect the computed value of
'font-feature-settings'.

The 'text-rendering' property was never formally defined to explicitly
enable font features, that was merely a behavior given it by user
agents, specifically Firefox and then Webkit. I don't think this
behavior is needed or desirable.
