TikZ: complement mark at coordinate

Question

I asked myself for the sake of interest: Is there possibly a possibility to add a mark=<...> to a \coordinate?

\documentclass[margin=3cm]{standalone}
\usepackage{tikz}
\begin{document}

\begin{tikzpicture}
\coordinate[label={[mark=*, text=red,left]:A}] (A) at (0,2);
\end{tikzpicture}

\end{document}

Note: The method

\foreach \P in {....} \draw[fill=white] (\P) circle (1.5pt);

is clear.

Answer 1

For what it is worth. This adds a plot mark and respects mark options.

\documentclass[margin=3cm]{standalone}
\usepackage{tikz}
\begin{document}

\begin{tikzpicture}[cmark/.style={append after command={plot[only marks,mark=#1] coordinates {(\tikzlastnode)}}}]
\coordinate[label={[text=red,left]:A},cmark={*,mark options={fill=white}}] 
(A) at (0,2);
\path (2,2) node[circle,inner sep=1.5pt,draw,label={[text=red,left]:B}] (B){} ;
\draw[stealth-stealth] (A) to[out=90,in=90] (B);
\end{tikzpicture}
\end{document}

Note, however, that I do not see any advantage compared to option B in which a node is used. Rather, I see a disadvantage since, if you connect either of them with an arrow, only the node knows the boundary, as illustrated. (Of course, in the node case you can connect to the center, too, by using B.center instead of B in the arc path.)
