Maybe add a download link to the homepage that links to a page that states the software is not yet available, or a greyed out download button that says “coming soon, click for more information” or something like that? Or perhaps make it a link to the downloads page on the docs - perhaps adding a bit more information to that page? ASOs are all looking for that coveted button, so why not give it to them? Some of them might then read the page and then not feel the need to post.
