I re-read the docs (always a good thing to do 😄) and realised that I was wrong on the "no task parallelism when tasks mount the same workspace" assumption. See https://tekton.dev/docs/pipelines/workspaces/#specifying-workspace-order-in-a-pipeline-and-affinity-assistants. I verified this to work as expected in our cluster, meaning tasks still run in parallel by default even if they share the same workspace (because they are assigned to the same node by default). This removes a big limitation outlined above - I've updated the proposal accordingly. Especially build tasks in monorepos will benefit hugely from this.

With regards to running tasks in parallel sharing files in the same workspace, there's a nice thread about it:

@felipecruz91 thanks for the link. I discovered this as well and the current proposal already takes this into account :)
