pgfplots move axis label together with axis line

Question

I would like to have the y axis labels of all plots in my document above the y axis line. Usually that is above origin but sometimes I have to move the line out of the way. What I am looking for is a method to tie axis line and axis label together, so that they move as if they were one.

Attempt

The pgfplots manual (chapter 4.9.10 Moving Axis Lines) states that axis y line shift allows to shift the axis line together with all its descriptions, but it does not seem to. The axis line moves but the label (which I consider a description of the axis line) stays in place. Even with ylabel shift the label does not move.

Quick fix

As a substitute I currently move the axis line to the far left and align the label north west. This is not really what I want but I can live with it.

\documentclass{standalone}
\usepackage{tikz}
\usepackage{pgfplots}
\pgfplotsset{
  compat=1.17,
  every axis/.style={
    axis lines={center},               %%% axes at origin by default
    every axis x label/.style={
      at=(current axis.right of origin),
      right,
    },
    every axis y label/.style={
      at=(current axis.above origin),   %%% y axis label above origin by default
      above,
    },
  },
}
\begin{document}
\begin{tikzpicture}
  \begin{axis}[
    ylabel={==y==},
    axis y line shift={0.5}, %%% attempt: moves axis line (but not the label)
    ylabel shift={0.5},      %%% attempt: has no effect
    % axis y line={left},                          %%% quick fix
    % ylabel style={at=(current axis.north west)}, %%% quick fix
    ]
    \addplot table {
      -1 -1
       1  1
    };
  \end{axis}
\end{tikzpicture}
\end{document}

The following image shows the output of the code above. The y label did not move with the y axis line. It is above the origin although it should have moved with the line.

The next image shows the result of the quick fix. Label '==y==' is above axis line.

You might be able to use

every axis y label/.style={
   at=(yticklabel* cs:1),
   %...

to position the axis label. The yticklabel* cs coordinate is described in section 4.9.1 Placement of axis descriptions of the pgfplots manual. (page 244-45 of the manual for version 1.18.1).
