Inconsistency in spelling conventions can lead to several issues:

* **Confusion for users and contributors**: Mixed spellings (e.g., "color" and "colour", "initialize" and "initialise") in the codebase create confusion about which variant to use
* **Harder code search and refactoring**: Searching for identifiers, method names, or documentation becomes more difficult when multiple spellings exist for the same concept
