The 1 was definitely made simpler from the old 204/205/215/216 routes which used to exist.
Simplifying route numbers is a good idea in theory but I think more could have been done for the Simplicity changes - unfortunately people don’t like change. The 62, 44, 66 becoming singular numbers made sense however I would have probably been more drastic with it.

The old 1 services would be run as normal but re numbered as the Dumbarton Express. All buses would run to Dumbarton and peak buses to Clydebank. After terminating at Dumbarton services would run at a reduced frequency from there in to Helensburgh and Balloch.
This is all fantasy of course
