I too always use "git checkout -b", but, like Junio, I don't think
this is an apt analogy. "git checkout -b" is shorthand for two
commands "git branch" and "git checkout", whereas "git checkout --to"
is not.

You can still do that with "git worktree new bar -b foo", which is
effectively the same as "git checkout --to bar -b foo" (with
s/checkout/worktree/ and s/--to/new/ applied), though perhaps you
don't find it as obvious or natural.

I'm not excited about keeping "git checkout --to" as an alias for "git
worktree new", however, removing it now should not harm us since, as
you say, it can be added back later if needed.

I'm not wedded to this particular argument order, though it does have
the advantage that it's clear which options belong to "worktree new"
and which to "checkout".
As for making <branch> optional and auto-vivifying a new branch named
after <path>, that's something we can consider later (I think).
