I think the idea is that though a fic and podfic are connected, they are still different fanworks. So if a fan believes that a podfic warrants its own page, I want to preserve that fan's right to make a page about that fanwork and not have it be altered to be about the fic, which is a different (though related) fanwork. (Fanlore has a policy about "letting fans define themselves," but I can't find the specific quote ATM).

I do agree with you that in many cases it makes sense for information about a fic and the podfic(s) based on it to appear in the same article, especially if there's not a whole lot to say about one or the other. In cases where there is not enough info for a whole page about the fic, it'd be reasonable to add a short "This podfic was based on the story by [so-and-so] which [minimal information]" on a podfic page the same way it's reasonable to say "This story was made into a podfic by [so-and-so] which [minimal information]" on a page about the story. But the idea is that they're separate fanworks and should be treated at such, even though one is based on the other. (FWIW, I feel the same way about fanart/fic trailers/whatever based on fic.)

Hope that makes sense!
