There are an infinite number of ways to make a project less fragile to changing market conditions. But you can't maximize all of it, it's all trade offs. Would making a project more resilient to semiconductor shortages increase vulnerability to other factors? Perhaps the increased electrical load pushes the battery requirements above the budgeted space. Perhaps the increased costs puts the product above the budget for customers, and making the project no longer viable in the marketplace. There are too many factors that I don't know about to possibly comment on all of it. The replacement of the MCU with discrete components was mentioned, and I commented on a few of the factors with could be involved with the decision, and did not claim to have made an exhaustive analysis of the product spec to determine why the choices were made.
