I think --xprofile is provided by libphutil but it doesn't know about Phabricator. It seems sort-of-nice-to-have to have the raw version, maybe. Not sure how easy it is to add --upload-xprofile to arc.

We could also add an arc upload-profile <file> or whatever, conceivably. This wouldn't be quite as seamless but we could add stuff like arc upload-profile --browse <file> more easily than --upload-xprofile --after-uploading-profile-browse-that-profile.

Not sure if it would be desirable but perhaps Arcanist would override libphutil's --xprofile and wrap around it to provide the suggested functionality? This is probably too magical. arc --upload-xprofile seems reasonable.

Personally, I've never had a need for the raw file.

--upload-xprofile is definitely more useful overall than --xprofile <file> since 99% of the time I've also done some approximation of that upload dance, it just feels a little weird for some stuff to take --xprofile <file> and some stuff to take --xprofile which takes no argument and means something completely different.

(We could also reasonably rename --xprofile to --xprofile-outfile or something, so the more-useful option can own the shorter flag.)
