...which is all extra setup that you need to do compared to if you weren't using lambda, in which case you'd already be set up using something like express. To be fair, it doesn't like it'd be too much work to do the conversion. But it would still be extra work compared to say moving something running on express and deployed in a container to another VPS and/or container hosting provider which would likely require no application changes at all.

There are services that offer compatible APIs to Lambda, in which case there's also no effort.

You could be switching from an integrated http server to using WSGI, which is almost identical to the effort I described. Who cares about the twenty minutes of work? It's "less portable" in such a trivial way.
