At least in the tests, using the empty string for
`GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME` is equivalent for not setting it at
all, i.e. to trigger the fall-back.
So yes, I totally agree that triggering an interactive prompt by the empty
value is not really a good idea (nor a particularly intuitive behavior).
With your idea to special-case any value starting with a colon, `:ask:`
seems like a saner approach.
Having said that, I would still favor the fall-back `main` over this idea:
it is a much smaller (and less annoying) change of behavior to use a less
loaded name than to change from a previously non-interactive to a
now-interactive operation.
As to using the base name by default: I don't think that is a good idea at
all. Not only doesn't it work when you run `git init` in the root
directory (which some people do, and that's totally okay with me), it also
does not work with any base name that isn't a valid ref name. Try this at
home:
$ git check-ref-format --branch "My Documents"
fatal: 'My Documents' is not a valid branch name
So while it is a cute idea, in general it will simply fail, and is
therefore worse than any alternative that does _not_ fail in general.

Indeed. In the spirit of minimizing disruption (as promised in
https://sfconservancy.org/news/2020/jun/23/gitbranchname/), I would like
to stay away from changing the default behavior _that_ much.
My current plan is to implement a warning in `git init` (much like the
`pull.rebase` one, which I thought would raise outcries of frustration,
but to my surprise this did not happen, and `git init` is _a lot_ less
common than `git pull`).
This needs to be done with care, obviously. I haven't looked yet, but I
think there is a chance that `git clone` would implicitly look at
`init.defaultBranch` only to override it later by the name of the remote
primary branch. In that case, we obviously do not want to warn the user
because the `init.defaultBranch` value is not actually used.
Ciao,
Dscho
