Justify by correctness, never by convention.

The trigger

You defended a design by pointing at what the codebase already does. That is not a correctness argument. Re-derive from first principles.

The core

If a codebase named every variable pizza1, pizza2, pizza3, that would not make those names good. So "it's what the codebase uses" is never a reason a design is correct. It is incidental. Prevalence is not evidence.
