That's for Cub Scouts. For Scouts BSA, the current plan is to have boy-only troops and girl-only troops. They can share the same troop number, committee, budget, etc, but only the Scoutmaster has to be different.
I foresee that changing or troops taking initiative and organizing differently unofficially, but that's the current plan.
Venturing Crews and Sea Scouts, both of which are part of BSA, have been co-ed for a long time. My initial research was not particularly fruitful, but I think that they've been that way since their respective inceptions. There's also no gender-specific leadership or structure.
My son just switched to Sea Scouts after attaining his Eagle Scout rank and my daughter just started Cub Scouts as a Tiger. We've been really impressed with how the Sea Scouts aren't making a big deal about the young women in the program. The only thing we run into is old men calling them "gals". I didn't know that was a pet peeve of mine, but you learn something new every day.
Comparatively, the Cub Scouts are constantly creating awkward situations in relation to the girl dens. Some of that is caused by BSA youth protection guidelines (girl dens must always have a female adult present), but other times it's about over-correcting little boys' behavior in front of little girls. It's still very new and I'm sure that everyone will adjust to something that doesn't require so much effort.
I very much hope that BSA can get out of its own way as more girls move into troops and just take notice of what's been accomplished by their existing co-ed programs.

Venturing Crews and Sea Scouts were both part of Exploring in 1969 when the program went co-ed.

There are, actually. Quoting the current edition of the Guide to Safe Scouting:
"Two registered adult leaders 21 years of age or over are required at all Scouting activities, including meetings. There must be a registered female adult leader over 21 in every unit serving females. A registered female adult leader over 21 must be present for any activity involving female youth."
Alternatively they do have explorers scouts as a coed part, and those are often attached to a regular troop, so they already have this for older scouts.
