Some quotes to provide context.

"I read several times that ideally I should avoid inheritance with ABCs and if I do, then from a standard class. That is, I should avoid creating a typical base and subclass construct that is used in a strategy pattern, for example."

I've reached the point where progress is clearly impossible. A bad decision a few weeks ago has reached it's inevitable conclusion. I've made a terrible mistake. About 1,000 lines of code -- and tons …

This was fun to read. It has some nice examples.

I submit that the order of presentation (S, O, L, I, D) is misleading. The acronym is fun, but awkward.

The SOLID design principles beat the design boundary issue to death. Here are the principles in my preferred order. (See https://www.linkedin.com/learning/learning-s-o-l-i-d-programming-principles)

1. Interface Segregation -- minimize the boundaries. Do this first.
2. Liskov Substitution -- keep the boundaries consistent. Do this for hierarchies.
3. Open/Closed -- keep the boundaries stable …

Sometimes we call them "Belt and Braces" solutions. As a former suspenders person who switched to belts, the idea of wearing both is a little like over-engineering. In the unlikely event of catastrophic failure of one system, your pants can still remain properly hoist. There's a weird, but defensible reason …
