I use to work at a company whose product had multiple versions of Java over its existence (literally think from Java 5 to Java 18), depending on the major product support versions (yes we had clients still on 1.0 system from the early 2000s, they were mostly regional banks). Worktrees made working on that monolith easier to do my types of tasks (updating tests that were specific to the UI team I was on, also the only person willing to touch java code). It sounds kinda backwards, but if you have to support multiple versions of a product that still brings in hundreds of millions in revenue it's nice to use git worktree to basically check out different versions of your product in time.
