It almost figuratively killed me, but iteration number... 4? on shell completions going for a PR this weekend. I finally bit the bullet and added a new builtin goal

completion-helper

which handles all of the heavy lifting and a 10-liner for the bash completion file itself. No more per-repo statically generated bash files - so this should be fully portable between projects. Wayyyyy faster than I expected it to run too (after the first load, anyways) Gotta clean this up, but in case anyone is interested in how much simpler it's become: https://github.com/sureshjoshi/pants/commit/4279117b642ea630eab1f0c769bf9cdeec54eec7#diff-9b0a71ccae10fb1c834ed0ef5[…]7e1219682a3e1d04e6baebd9521050

super cool!
