I assume you do not use TypeScript but JavaScript? With TS your POs are basically discoverable with source-code completion and statically typed.

   await page.getStartedLink.click()
   expect(page.installationHeadline).toBeVisible()

Another note on your specific example: You are probably in the US and only have a single-language project. I am a Frontend Contractor in Europe and for the past 10 years didn't have a single project that was single language, hence the "hasText" selector would always be off-limits. Instead, very often we used the react-intl identificator as text content for code execution - which would make the above example look much more unreadable without POs, while with POs the code looks the same (just your PO looks different).
