Yep.
I'll do one better for reference:

Compared to Bless:
PRO: Lasts 10 times longer (major since this allows it to span multiple encounters, including social or exploration challenges)
PRO: No concentration required (major since it allows the cleric to cast spells with concentration--like, oh,
bless)
PRO: Doesn't use a spell slot for 2-6 uses depending on character level
PRO: Can also be used for ability checks (mostly making
guidance useless)
PRO: Can affect up to twice as many creatures (fairly quickly depending on play speed matches or surpasses bless)
PRO: (vs. Guidance) Can affect 2-6 creatures per round for ability checks instead of just one creature per round
CON: Can only impact attacks, saves, or ability checks once during a turn (major when Extra Attack comes online or multiple saves are required)
CON: Might only affect two creatures (fairly quickly this goes away IME)
CON: Affected creatures must be within 30 feet of another affected creature
when they want to gain the benefit. They can wander all over otherwise when they don't care about the affect.
So, IMO yes I would go beyond "quite solid ability". But, considering what they did with Twilight Domain, I am not surprised. I would be floored (I am certain) if the PHB features were revamped to match the power creep in Tasha's.
*I will state that I don't know if "broken" isn't too strong a term used in the other thread, but jeez this feature is OP regardless.
