Sure, you can write a bunch of tools to work around the crufty, terrible development environment's shortcomings. But ultimately, you are just locking yourself further & further & further in to the hostile, hard to work with environment, bending yourself into the bizarre abnormal geometry the serverless environment has demanded of you.

To me, as a developer who values being able to understand & comprehend & try, I would prefer staying far far far away from any serverless environment that is vendor locked. I would be willing & interested to try serverless environments that give me, the developer, the traditional great & vast powers of running as root locally that I expect. Short of a local dev environment, one meets both vendor lock in, & faces ongoing difficulties trying to understand what is happening, with what performance profiles/costs. I'd rather not invest my creativity & effort in trying to eek more & more signals out of the vendor's black box. Especially if trouble is knocking, then I would very much like to be able to fall back on the amazing toolkits I know & love.
