I think you might be confusing end-to-end (E2E) tests with other types of testing, such as unit and integration tests. No one is advocating this approach for unit tests, which should still run in their entirety on every pull request. Running all E2E tests in a pipeline isn't feasible due to time constraints (takes hours). Most companies just run these tests nightly (and we still do). Which means we would still catch any issues that slip through the initial screening. But so far, nothing did.
