I didn't really feel like the benefits of packages like Serverless and Apex were worth it for me, as they're not solving that big of a problem, and you'd replace it with lock-in to even less mature products. That said, the current lock-in is not that bad, just good to be aware of and keep an eye on.

I hope that the annoyances are temporary indeed, but that doesn't buy me anything today :) That said, I think for almost all my drawbacks it holds true that they're likely to grow less and less significant, so if serverless is not worth it for you today, it's still worth it to keep an eye on.

Edit: I should perhaps also link the shim that I'm using. It's slightly longer, also specific to my relatively loose configuration of API Gateway, and also simulates S3's client-side file upload functionality. As you can see, it's really not that bad: https://gitlab.com/Flockademic/Flockademic/blob/dev/app.ts
