UPDATE: Android updated, and now Chrome tab groups are enabled permanently. I'm installing Firefox and Opera to see which is best. Abandoning Chrome. Tab groups are AWFUL and AWKWARD. They need to be OPTIONAL. The day they become irreversible is the day I will switch browsers. It's so bad that I've disabled updates, for fear of the next time my browser suddenly becomes unusable. I remember the good old days when Chrome was the lightest, fastest browser. Now it's more bloated with every release.
