Now... we're only about 600ms away from shell completions running directly on the

./pants help

command, without being infuriating to use Or... some sort of help cache

Not surprising, but happy to note that in-repo plugins appear to be picked up as well:

⏺ scratch/pants-plugins % ./pants help swift                                                                                                                                                                               

`swift` subsystem options
-------------------------

The Swift programming language (<https://www.swift.org/>).

Compilation occurs via the underlying LLVM front-end. ie. "swift-frontend -frontend", through `swiftc` See <https://www.swift.org/swift-compiler/> for more information.

      A list of paths to search for Swift.
      
      Specify absolute paths to directories with the `swiftc` binary, e.g. `/usr/bin`. Earlier entries will be searched first.
      
      The special string `"<PATH>"` will expand to the contents of the PATH env var.
