I would bet that approximately 100% of people advocating for funded childcare programs++ would want to avoid the "putting infants in daycare for 8-10hrs/day" scenario.

In what way? I've seen many people advocate for universal childcare as a way to get mom back to working full time as quickly as possible. I've also seen it framed as a way of leveling the playing field, so women are less disadvantaged from men as a result of childbirth / care.

I find that, if anything, there is little to no stigma to getting your child in daycare ASAP after maternity leave ends and going back to working full time. That's "infants in daycare for 8-10hrs/day".

Why do you think that?
