This is absolutely true and fair. Thank you very much OP for your suggestion, romantic content, fair for all companions, bringing happiness and joy to all players, with every possible LI and in all their paths, good and evil - this would have been a worthy ending to the game and would have brought joy to all players! Even on the trivial example of the epilogue - every LI should have hugs and kisses, this should have been done in the first place, adding a party at the end of the game. Friendly hugs could have been implemented later, it's not that important, and even frustrating for the player when you can hug friendly companions but can't touch your beloved in any way. If one person has a kiss, then everyone should have one - it would be fair.
There are so many animations and voiced lines available that could be repurposed and tweaked to in order to make this achievable without recording new voice lines or creating brand new animations. Equaling out content is not an unachievable task and does not necessarily require brand new cinematics. Modders are already doing this/fixing bugs but people shouldn't have to rely on mods for bugs to be fixed or content to be equal, and many console/Mac players will never be able to access most romance mods anyway due to needing script extender.

Content that is already voiced and contained in the game files would just be sad not to add. It wouldn't require a lot of resources, it's already created, just need to make it work in the game itself. Perhaps this could be done with a hotfix. Really wish the already existing great voiced lines were not wasted.
