Currently there is this note in this section:

For legacy reasons, UAs must also support the alternate keyword distribute which must compute to inter-character, thus having the exact same meaning and behavior.

Looking at browser support for text-justify:

• Chrome only supports the property behind the experimental web features flag
• IE (which used to support this value) is now retired
• Safari has never shipped text-justify

...which leaves Firefox being the only browser supporting the CSS property.

I suggest that we remove this note from the spec, since there is no clear win in web compatibility in supporting this.
