The limits are there specifically to help in that transition, to avoid the problem described in the chart. They're a crucial learning extracted from the beta we ran.
The reason I'm still on DO is because I need dependencies that are both large and trivial to install in docker vs. creating a custom EC2 image. To make it clear I was hoping to deploy a docker container with ffmpeg to support long running video conversions whilst benefiting from easy deploys and on demand pricing. It seems like the potential for this alluded to in the serverless docker announcement has been removed?
I can see how this V2 makes serverless simpler but the strict limits will mean that transitioning a monolithic app requires a lot of work up front. Increasing the limits would reduce that friction greatly. Whilst not best practice deploying an existing express app and have it 'just work' is a compelling reason to go serverless.
Especially compared with usernames and password, which is basically built in to anything already.
