Here’s the statement from a Google engineer:

“Chrome is no longer used as a WebView implementation in Q+. We’ve moved to a new model for sharing common code between Chrome and WebView (called “Trichrome”), which gives the same benefits of reduced download and install size while having fewer weird special cases and bugs.” Meaning is the Android package file of Trichrome. All Android apps and programs like Trichrome have a unique package name for identification purposes, and they contain important files.
