GM did it ALL the Time to dealerships as part #'s were combined and Homologation began on them. This caused some stacking in parts bins as ya never knew if you needed a new bin or it was a replacement part for a while. Models that shared drivelines, and or brake parts etc, and spanned many years, often got new parts, with new numbers and sometimes a new manufacturer. Ac Delco wiper blades that fit on factory Trico arms are a good example. By 1981 a 78 Nova Ralley brake hose was same as a 77z-28, and a 77 T/A , Ventura.. etc. there was over 20 different master cylinder numbers, merged into ONE.
I only use Dot 5 now in a car or truck that sits around. , No hassles, no unexpected paint stripping...
