Is it unusual for a SCOTUS disent to omit the phrase "respectfully disent" or the like?

I'd have been inclined to something a bit harsher than "With sorrow", but that's only one small reason I'm not a judge of any sort.

The current SCOTUS majority deserves scorn, contempt, and not one ounce of respect.

It isn’t unheard of - but is usually noticed as sending a message

I remember when RBG did in Bush v.Gore … “Supreme Court’s equivalent of a glove slap to the face”

2. This omission was intentional
