Your choice, your right.
Over the years we have developed our own standard for relative simple schematics of all our devices. We put all microcontroller lines into one bus and then each block takes from it some of them. There are no connections made out of bus (with just using labels). When during PCB design I see a need to use other uC pins I just replace labels near uC.
