Am I right in deciding that I cannot get a follower to accept the "blessing" from a standing stone? Since it requires the player to give an extra click to acknowledge giving up any previous effects, I'm assuming that's why nothing happens when I tell Jenassa to do it. She moves to stand nearby, but nothing happens and she gets no extra magic resistance from the Lord Stone. Same thing happens when I tried her on the Steed Stone. And the wiki doesn't list the effects (yet) to give them with the console.

if you read the book about the stones (i think theres 1 in aradias cauldron in whiterun) the author is talking about how no matter how many times he touches the stones nothing ever happens, so he will wait at the stones and keep trying while waiting for someone to come who can use them, and also on the run to Riverwood after leaving Helgen, your choice of guide will comment about people touching the stones in the hopes they would work again, but have not in a long time. Basically just saying they work for the Dragonborn but not your average person. too bad, it would be nice to add one to your follower lol
