Do you need a glide path for AOA?

So I actually just learned about AOA and that family of funds. Most of my knowledge in terms of investing and stuff is the general VT/VTI/VOO stuff and slowly add in bonds, but with AOA and those family of funds they automatically have bonds So do people just keep buying AOA early and don't stop or do they start to buy AOR or AOK as they get closer to retirement? or do they sell the AOA when their tax brackets are lower and glide it over that way? I'm not going to change where I'm at, but I'm just curious as to this family of funds and what conventional wisdom is around them. Thank you!
