On the one hand, some might argue that the development of automation frameworks for testing, like Cypress, is a specialized skill that is essential for ensuring the overall quality of software products and is in fact coupled with QA, and it matters a lot that you should have some knowledge and understanding on how QA works for that. On the other hand, others might say it is a normal product development like any other product. In other words, developing testing tools like Cypress isn't QA, and the only relation to QA is simply in marketing and target audience, and you don't need to have much experience or knowledge about QA beyond that to ensure the proper development of such software.
