Rotate full circuit, without any of the text

Question

I have a schematics (grossly simplified in the below MWE) that I would like to use both upright and rotated, from the same source (i.e. the only difference should be in the \begin{tikzpicture} parameters, not in the code of individual nodes).

The problem is that if I use rotate without transform shape, the whole picture falls apart; and if I use it with transform shape, then the labels are rotated as well. I'm looking for a setting that behaves like transform shape, but applies a reverse rotation to all text labels.

Based on this answer, I tried the following, but it doesn't seem to do anything:

\tikzset{
  every label/.append style={reset transform},
  reset transform/.code={\pgftransformreset}
}

Full code:

\documentclass[varwidth,margin=3mm]{standalone}
\usepackage{tikz}
\usepackage{circuitikz}
\begin{document}
\newcommand{\schematics}{
  \draw (0,0) nodedipchip, num pins=6{\ttfamily ADD};
  \draw (add.pin 1) -- ++(-1,0) node[left]{\ttfamily x0};
  \draw (add.pin 3) -- ++(-1,0) node[left]{\ttfamily y0};
  \draw (add.pin 5) -- ++(1,0) node[right]{\ttfamily z0};
}
\begin{tikzpicture}
  \schematics
\end{tikzpicture}
\begin{tikzpicture}[rotate=-90]
  \schematics
\end{tikzpicture}
\begin{tikzpicture}[rotate=-90,transform shape]
  \schematics
\end{tikzpicture}
\end{document}

No, it will not work, sorry.

I tried to correct this last year, but changes where too invasives and... scary: https://github.com/circuitikz/circuitikz/pull/257

What you can do is rotate \myangle with transform shape, and counter-rotate the labels manually with a \rotatebox{\myangle}{...} command where needed:

\documentclass[varwidth,margin=3mm]{standalone}
\usepackage{tikz}
\usepackage{circuitikz}
\begin{document}
\newcommand{\myangle}{0}\newcommand\slap[1]{\rotatebox{\myangle}{#1}}
\newcommand{\schematics}{
    \draw (0,0) nodedipchip, num pins=6{\slap{\ttfamily ADD}};
    \draw (add.pin 1) -- ++(-1,0) node[left]{\slap{\ttfamily x0}};
    \draw (add.pin 3) -- ++(-1,0) node[left]{\slap{\ttfamily y0}};
    \draw (add.pin 5) -- ++(1,0) node[right]{\slap{\ttfamily z0}};
}
\begin{tikzpicture}
  \schematics
\end{tikzpicture}
\renewcommand{\myangle}{90}
\begin{tikzpicture}[rotate=-\myangle,transform shape]
  \schematics
\end{tikzpicture}
\end{document}
