In the following example it is understandable that the second tikzpicture is the default behavior since it is same as how label works (see attached PDF).

\documentclass[tikz]{standalone}
\begin{document}
	{
		\makeatletter
		\tikzset{
			every pin/.append style={
				anchor={180+\tikz@label@angle},
				anchor/.code={} % locally disable `anchor`
				                % so that `anchor=@auto,` at line 647 and 677
				                % do not overwrite anchor
			}
		}
		
		\tikz{
			\draw foreach\ang in{10,20,...,360}
				{(0,0)node[pin=\ang:pin]{base node}}
		}
	}
	\tikz{
		\draw foreach\ang in{10,20,...,360}
			{(0,0)node[pin=\ang:pin]{base node}}
	}
\end{document}

My feature request is to make the fitst tikzpicture the default behavior;
or at least make it less hacky.
Currently I have to put anchor/.code={} in my implement because
at tikz.code.tex line 647 and 677 there are hard-coded anchor=@auto,.
Perhaps it is easy/possible to make it an option.

I'll fix the problem with anchor being overwritten as part of #774, but changing the default behaviour is rejected, thus closing.
