As stated, Blood Will Tell references the "Affliction"/"Divergence" backstory. Alien Spotlight: Vulcans mentions Vulcans having served on Starfleet vessels before. Alien Spotlight: Andorians uses the ENT-style Andorian design, the terms "Andoria" and "pink-skins," the concept of Andoria as an ice planet, architecture like that seen in "The Aenar," and the ushaan-tor weapons (which, yes, come from an RPG supplement, but I assume the specific look comes from ENT's production designers). AS: Orions alludes to Orion females' pheromonal control and uses the ENT-style design for its Tellarite characters. Intelligence Gathering uses ENT-style Andorians and Rigelians.
Regardless of its popularity, ENT is part of the tapestry of the Trek universe now, and writers will draw on whatever of its concepts they find worth using.
