HaLeiVi: Not everyone holds of Beyada either. There are some Rishonim who hold that Eid Echad Ne’eman B’Issurim does not apply to women for anything. The Mordechai points out that the reason we believe she was Tovel for this is only if we know her to be Shomer Halacha and therefore she has a Chazaka that she wouldn’t be Over on any Issurim (including Lifnei Iver so you can trust the Kashrus).
