Yes, yes I am lol
Theres some other flags you can adjust to get different responses as well, if you change the flag for Nerrasa [The person at Uveto station who sells heating belts] if you changea flag that says how many times you've sexed her, their dialog changes. FYI they seem to be planned to be a dominant character.
So there is quite a bit of hidden but planned dialog options and what not, much of that all being VERY old, like back when it was still Adobe? (I think it was adobe) So it could be that they've been forgotten about or just busy focusing on other content.
