Rather than documenting... want to assign suborbital/subo#344 to yourself and fix it in Subo directly?

Sure do! I'll close this, then.

I would prefer that we actually documented this because 1, we don't know when is this going to get fixed; 2, people might still be on old versions of subo for which it would be useful to mention this in the docs.

Laura and I are pairing on it in ~4 hours. :) Suspect the fix is one sed and done.

Cool! Do note though that some systems may have either, or both, so I don't think we want to favor any one of the compose-s, we should be able to use both. (probably more a note for suborbital/subo#344 )
