Are there any alpine rock routes that need a bivi? Routes like the Philipp-Flamm on the Civetta, Salbit westgrat, or those on the south face of the Marmolada are as long as they get (~35 pitches) and all normally day routes.
You can choose to bivi en route. I see the attraction of spending the night in a lovely spot. However climbing is rather less fun and much harder work carrying a pack and bivi gear. It's also likely to be significantly more dangeous as you'll be more tired, especially on the second day, and exposed to rockfall and unexpected bad weather for twice as long. In my view, it would be inviting trouble to bivi
on the Cassin route on the Piz Badile.
Cassin and Rebuffat may have bivied, and reading their stories perhaps encourages our romatic view of a night in the mountains under the stars. With modern gear and knowledge we don't need to bivi.
