BaV in addition to the retirement savings account

My AG offers attractive funding for BaV at Swiss Life. I calculated everything very conservatively because I'm actually not a fan of that sort of thing, but it's a good offer thanks to the Höhen AG subsidy and government funding. However, I am wondering whether, based on the current status, I would have a disadvantage if I opened a retirement savings account next year, i.e. if only one of these options is funded per citizen or something similar, then I would probably not apply for the BaV
