I addressed that very thing in my comment. The key being that it might prevent a handful of people from needing to ask. In no way am I expecting it to prevent asking entirely, as some people just refuse to look for information.
This web page is already very long. The itch system maybe does not allow page of contents or other ways to organize it, and there may be many issues to add.
Another way might be adding Frequently Asked Questions to the Wiki. If the wiki does get FAQ, it should be divided in non-spoiler and may contain spoilers sections.
Discord has FAQ channel, but it seems to contain only installation and update information.
That's a fine recommendation as well, I think. Adding it to the wiki's FAQ could help a lot, but it'd also help, in some small way, to put it here on the main page.
For one, I'm sure not everyone is even aware of the wiki, and if they are there's no telling whether they've been there before. I've been following the game for years and I've not once visited the wiki. Secondly, with it being on the main page, likely directly by the 'planned theme' it'd be right near where people would see that pregnancy is a planned theme; as I'm sure there are a number of people that read through the page, see that, and then ask about when it'll be added (or if it's already been added).
Just to reiterate, I do think it'd be a grand idea to add a comment about it in the FAQ on the wiki, but also to the direct game page here - where people will be able to find it a touch more directly. Even if it won't prevent many people, it just needs to help some.
