I never said the extra proficiency was worthless, my first sentence says they're nice. This post is specifically about the unique features of each. True strike in particular is absolutely worthless, and Sacred Flame is not far ahead. Casual players could waste the pick on heavy armor proficiency if they don't know about minimum STR requirements. Prot from Evil and Good has some uses in certain situations (especially with how the AI handles targeting right now). However, by the time you get to a point where Prot from evil and good has a use, you might not want to use a Ranger action for utility when they have access to multiattack and are generally going to want to deal damage.
To clarify I think Larian is on the right track with these changes, I just think they need to buff these options to make them feel like they actually do something impactful.
