Even among royals, full siblings getting married/having sex was not exactly "commonplace", ie ordinary or the norm.
Occurred more than many think, sure. But it was still the exception, not the norm.
I hadn't intended to make it sound like everybody was coupling up, but the exploration was certainly more common than modern media suggests, based on actual historical records.
I also think a lot of those were half-siblings...
There may be exceptions with a few ancient cultures, but again, it was generally not the norm.
Again, didn't mean to suggest it was 'the norm', but yes, there were a lot of half-sibling pairings. No doubt due to an also extreme number of unfaithful partners.
And there is some science behind siblings, or even non-related children, who grow up together developing a natural sexual aversion to one another...

. Just as on the flipside siblings who don't grow up together and meet later in life often have a much stronger attraction to one another. It's happened often enough with those who were split due to parental divorce/deaths or being adopted. There was one that popped up in the last decade about a Brazilian couple. They had married and even had a child for years before they found out.
Various cultures have their different lines that shouldn't be crossed. In some it's perfectly fine for aunt/uncle to pair up with neice/nephew, in others they don't care about cousins. Some take a more clan-based approach, where it doesn't even matter if you share blood with somebody in the clan, you have to pair up with somebody from outside. The most universally proscribed sexual relationships are between parents and their direct offspring.
Which, when going back to Artemis, really boils down to how one views their MC's relationship to the gynoid in question. I don't have any paternal feelings, just as I also don't feel anything resembling a pet/owner relationship with Koko. I actually find her a bit less appealing with the full flesh face, I don't know why. There was something about the non-fleshy jaw that accented her look in a way I liked. But I don't feel like there are any crossed boundaries, especially if as she develops and adapts she's the one who may try to initiate.
The weirdest part of it, to me, would be because it would feel like being hit on by a 15 year old girl rather than a grown woman. But just like the (lack of) parental feeling angle, that's a
me issue, and not a fault with the game narrative in any manner. If a hot robot girl hits on you, the only precautions you need to take are to make sure she doesn't have hydraulic strength enough to rip your dick off.
