That's crazy, seeing that confirms to me that there was 100% only a romance path for Halsin up to patch 6, because to me "added" means that there simply wasn't a platonic path before.
Do take into account (and perhaps this is me thinking in way-too-good faith) that maybe it's just written weird and instead means something like "you could be friendly with Halsin before but it would just result in less content and weird silence from him" or something like that. It's really so unbelievable to me I kind of think I've gotten it wrong, somehow. Weirder misunderstandings have happened before.
As for whether the boards are looked at or not, in theory they are. However they've stated they're only going to be working on bugfixes rather than story stuff now, past crossplay and camera mode- unsure if they'd count this as a bug or story-related.
