Summary: Ref T13098. Historically, Phabricator was split into three parts: - Phabricator, the server. - Arcanist, the client. - libphutil, libraries shared between the client and server. One imagined use case for this was that `libphutil` might become a general-purpose library that other projects would use. However, this didn't really happen, and it seems unlikely to at this point: Phabricator has become a relatively more sophisticated application platform; we didn't end up seeing or encouraging much custom development; what custom development there is basically embraces all of Phabricator since there are huge advantages to doing so; and a general "open source is awful" sort of factor here in the sense that open source users often don't have goals well aligned to our goals. Turning "arc" into a client platform and building package management solidify us in this direction of being a standalone platform, not a standalone utility library. Phabricator also depends on `arcanist/`. If it didn't, there would be a small advantage to saying "shared code + client for client, shared code + server for server", but there's no such distinction and it seems unlikely that one will ever exist. Even if it did, I think this has little value. Nowadays, I think this separation has no advantages for us and one significant cost: it makes installing `arcanist` more difficult for end-users. This will need some more finesssing (Phabricator will need some changes for compatibility, and a lot of stuff that still says "libphutil" or "phutil" may eventually want to say "arcanist"), and some stuff (like xhpast) is probably straight-up broken right now and needs some tweaking, but I don't anticipate any major issues here. There was never anything particularly magical about libphutil as a separate standalone library. Test Plan: Ran `arc`, it gets about as far as it did before.
