What's the motivation behind the push to separate axes?  Keep in mind
that the 'font-feature-settings' property *does* provide access to the
separate features.  I think having a single axis covers the majority of
use cases (e.g. discretionary-ligatures).

The 'clig' feature is enabled with 'calt' via the 'contextual' value of
'font-variant-alternates' and is assumed to be on by default.

For 'rlig' the assumption is that it's always enabled when necessary,
i.e. it's a default feature for OpenType fonts.  But adding a note to
explain this explicitly would make sense.
