Espaciado vertical: entorno blkarray dentro del entorno de alineación

Question

He creado mi propio comando que crea vectores de columnas etiquetadas usando elblkarrayambiente. Los problemas de espaciado vertical surgen cuando el comando se usa dentro del alignentorno. Generaba demasiado espacio vertical.

Lo he usado \\[-3em]justo después \begin{align}y justo antes \end{align}; pero no quiero ajustarlo manualmente cada vez. Además, eché un vistazo aeste, Pero el problema persiste.

\documentclass{article}
\usepackage{blkarray}
\usepackage{amsmath}
\setlength{\parindent}{0pt}

\newcommand{\colVectorLabelled}[2]{
  \ensuremath{\mathrm{#1} = 
    \begin{blockarray}{*{1}{c} l}
      \begin{block}{*{1}{>{$\footnotesize}c<{$}} l} & \\\end{block}
      \begin{block}{[c]>{$\footnotesize}l<{$}}#2\end{block}
    \end{blockarray}    
  }    
}
\begin{document}

  \textbf{The} \verb|\blockarray| \textbf{environment alone}: Some filler text
  some filler text some filler text some filler text some filler text some filler text.\\
  \colVectorLabelled{X}{1 & $0_{2}$\\0 & $1_{2}$\\}

  \textbf{The} \verb|\blockarray| \textbf{environment inside} \verb|\align| 
  \textbf{environment}: Some filler text some filler text some filler text some 
  filler text some filler text some filler text.\\
  \begin{align}
    \colVectorLabelled{X}{1 & $0_{2}$\\0 & $1_{2}$\\}
  \end{align}
  More filler text filler text filler text filler text filler text filler text filler text
\end{document}

Gracias de antemano :)

Aquí hay una solución alternativa, con \useshortskipfrom nccmathpara el espacio anterior y una sencilla \vskip -2expara el espacio siguiente:

\documentclass{article}
\usepackage{blkarray}
\usepackage{amsmath, nccmath}
\setlength{\parindent}{0pt}

\newcommand{\colVectorLabelled}[2]{
  \ensuremath{\mathrm{#1} =
    \begin{blockarray}{*{1}{c} l}
      \begin{block}{*{1}{>{$\footnotesize}c<{$}} l} & \\\end{block}
      \begin{block}{[c]>{$\footnotesize}l<{$}}#2\end{block}
    \end{blockarray}
  }
}

\begin{document}

  \textbf{The} \verb|\blockarray| \textbf{environment alone}: Some filler text
  some filler text some filler text some filler text some filler text some filler text.\\
  \colVectorLabelled{X}{1 & $0_{2}$\\0 & $1_{2}$\\}

 \textbf{The} \verb|\blockarray| \textbf{environment inside} \verb|\align|
 \textbf{environment}: Some filler text some filler text some filler text some
 filler text some filler text some filler text some filler text some filler text some filler text.\useshortskip
 \begin{align}
 \colVectorLabelled{X}{1 & $0_{2}$\\0 & $1_{2}$\\}
 \end{align}\vskip-2ex
 More filler text filler text filler text filler text filler text filler text filler text
