This requirement to always take a second sub-command makes it different from `swift build` and `swift test` too. Are there any commands to `swift` current that require a sub-command to work?

I agree with this part about package sounding like an imperative verb. Do you have an alternative proposal that you like better, though? In practice, this confusion will be quickly mitigated as `swift package` simply shows the help.

If separate, the obvious name would be `spm` as that's what we all call it anyway. `swiftpm` as noted in the alternatives section would also work. If we have to have it as a subcommand of `swift` then, I'd rather have `swift pm` as that way the command is obviously the third word in `swift pm init`.

That way it all happens in one go rather than as two stages which means only one announcement point is needed. The band-aid has to be ripped off at some point as `swift build --init` won't work in v3, so better for it to be gone before new developers find it during when downloading the preview released and then have to learn the new way.

I agree.

(I'm not ignoring `spm` parts of your email, just plan to reply to them in bulk once we have received more feedback).
