I'm not sure about this.

Often after you started to code something while on 'master' you
realize that work is not trivial and needs its own branch and
then "checkout -b" without having to say 'master' (or HEAD) is
very handy.

I think requring an explicit fork-point when you are _not_ on
'master' might be a better behaviour.

In other words, you allow "checkout -b" (and "branch") to
default to HEAD only while on the branches marked in your
configuration file:

Then:

	[branch]
        	allowbranchbydefault = main
        	allowbranchbydefault = test

can be used to say "while on 'main' and 'test' branch, 'git
checkout -b' and 'git branch' without branch point defaults to
the current branch".

You could turn it around and make it a per-branch configuration,
like:

	[branch "main"]
        	allowbranchbydefault = true
