I didn't want to see "oh you are calling lazy_init here but you can
delay it even further" kind of comments that is wrong and wastes our
time.

It is the complete opposite of what I meant.

Changing

	git_am_config(...) {
		return git_default_config(...);
	}
	... 
		git_config(git_am_config);

to

	/* no git_am_config() */
	...
		git_config(git_default_config);

is perfectly fine as a clean-up post series.

If we are moving away from git_config() callback style, and move to
git_config_get_*() style, the upthread already said it does not have
a good risk/benefit ratio, but if we were to do so, then we should
not leave some still using the callback style while others using
git_config_get_*(), which will lead to configuration read in a wrong
order and easily breaking precedence rules.

And if we were to move away completely from the callback style, then
I do not see a point to build such a series on top of the lazy init
patch, which is about staying with the callback style.

So, that is exactly why I asked the question after seeing it was
marked to apply on top of the lazy init thing, which did not make
sense to me.
