I agree. It shows lack of faith in your work and your audience. It also takes away the audiences’ sense of “getting it” when they look and notice, which makes your audience feel smart and in conversation with you.
Reminds me of those little panels beside paintings in a gallery that sometimes tell you way too much about what the artist was thinking. The work itself is supposed to be communicating, if you need supplemental material then you may have failed somewhat in the original work.
Those little panels are there to prevent from offending the well-educated and the ignorant both from the abominable curse of critical thinking and inconclusive analysis, but I suspect you know or intuit that.
There have always been two art audiences: Those partaking and intaking the artist’s works, and those doing the same out of the social spectacle they engender.
