“Why mess with worktrees when every thread can get its own computer?”

A prominent practitioner dropping worktrees for a remote machine per agent thread, where the agent installs ClickHouse, Kafka or whatever it needs. Replies split on it. One notes that worktrees separate files but two agents can still change the same running service. Another already skips worktrees locally with a scratchpad directory per agent and OCI containers. Alongside Shopify's remote environments, this suggests the isolation boundary is moving from the file tree to the whole machine.
