What is the function of permanent acolytes and lectors in the Catholic Church?

Prior to this [motu proprio](http://www.vatican.va/content/francesco/en/motu_proprio/documents/papa-francesco-motu-proprio-20210110_spiritus-domini.html) the only purpose of the order of acolyte or lector in the Catholic Church that I knew of was to prepare permanent deacons for ordination. So, if the purpose is expanded to all lay people, what function will acolytes perform in the future? Will we be expecting itinerant acolytes going from parish to parish helping at masses? Will we be wowed by one superior lector?
