This specification assumes a use of selectors that is consistent with the CSS2 Specification. Reading Systems must support all CSS2 selectors, including pseudo-elements and pseudo-classes. However, certain pseudo-classes may not be applicable to all Reading Systems (e.g. hover for devices with a touch screen) and may not result in any rendering on such devices.

(Significant clarification highlighted in red.)
So compliant renderers are required handle :first-letter, :first-line pseudo elements and the :first-child pseudo-class, among others.
This has always been the case, but some implementations have chosen to assume that it wasn't required. This clarification shows that this assumption was a mistake.
