What's more likely to fail or cause issues? Dependencies failing and parsing errors are usually handled by the build system (type checkers and linters). In the case where they are triggered in production, it can be easily caught by monitoring services like Sentry. Ideally any changes are manually tested before releasing, and a bug in one part of the app that's being worked on is not likely to affect a different section, e.g. not necessary to retest the password reset flow if you're working on the home dashboard. Having a suit of usually flaky end-to-end tests seems like the most sloppy and cumbersome way to ensure the application runs fine, especially for a small team.

That sounds suspiciously like “don’t need to test if I use static typing and monitoring”.

That is one can of worms. First, during normal development work it is very common to modify some part that affects multiple parts of the app. In fact, it is inhuman to know exactly what it affects in a big app (ergo, testing). Second, while manual testing is a kind of e2e testing, it is not feasible in a bigger application.

Then make them not flaky. It’s amazing what can happen if something stops being treated as an afterthought!
