For some people, it's no big deal to take apart a bottom bracket but for others it's intimidating. Larger vehicles have a better regenerative braking coefficient. Riding on pavement this only becomes an issue at pretty high power levels (>1500 watts), but when climbing hills on loose gravel or dirt roads, you can end up with the front wheel skidding pretty easily even at fairly modest powers unless you deliberately lean over the handlebars. Regenerative braking lets EVs and hybrid vehicles store some of that kinetic energy in the battery to use when you accelerate again. The main advantage of this system is that its much lighter than a hub motor system, since youre not adding any extra motors or batteries to the bike.
