In my opinion, since Larian advertised all those kisses as a Valentine Day gift to all the fans, it's really valid to ask them to make this equal. It's very weird to say: "This is a present" and then give someone everything (like Gale) and then some other companion pretty much nothing.
It looks pretty offending and unfair.
If Larian themselves didn't treat these kisses as such a big deal, then yeah, I would have agreed it's not that important. But now it just gives the wrong vibes, to put it mildly.
