Uppercase chapter with KOMA-script

Question

It has already been mentioned that it could be tricky to get uppercase letters in chapter for scrbook. However, the solution in Using \MakeUppercase in \@startsection works for scrreprt.

The solution used in tudscr adds a custom command to make the text uppercase, but then chapter has to be redefined.

\makeatletter
    \newcommand*\mymakeuppercase[1]{%
        \ifdin{\begingroup\MakeTextUppercase{#1}\endgroup}{#1}%
    }
\makeatother

Any other alternative, that would be applicable to all koma scripts?

MWE:

\documentclass[chapterprefix=on]{scrbook}

% Fix \MakeUppercase
\usepackage{makerobust}
\makeatletter
\MakeRobustCommand\@hangfrom
\newcommand*{\ModMakeUppercase}{%
    \MakeRobustCommand\@svsec
    \MakeUppercase
}
\makeatother

\addtokomafont{part}{\MakeUppercase}
\addtokomafont{chapter}{\MakeUppercase} % <- doesn't work
\addtokomafont{section}{\ModMakeUppercase}
\addtokomafont{subsection}{\ModMakeUppercase}


\begin{document}
\tableofcontents
\end{document}

Update

Since KOMA-Script version 3.19 the recommended way is redefining \sectionlinesformat, \chapterlinesformat:

\documentclass[chapterprefix]{scrbook}[2015/10/03]

\makeatletter
\renewcommand\sectionlinesformat[4]{%
  \@hangfrom{\hskip #2#3}{\MakeUppercase{#4}}%
}
\renewcommand\chapterlinesformat[3]{%
  \@hangfrom{#2}{\MakeUppercase{#3}}%
}
\makeatother
\renewcommand\chapterlineswithprefixformat[3]{%
  \MakeUppercase{#2#3}%
}
\renewcommand{\sectioncatchphraseformat}[4]{%
  \hskip #2#3\MakeUppercase{#4}%
}

\usepackage{blindtext}
\begin{document}
\tableofcontents
\listoffigures
\chapter{Test}
\KOMAScriptVersion
\blinddocument
\end{document}

There is a problem in KOMA-Script Version 3.16 (and 3.15). As a workaround:

\documentclass[chapterprefix=on]{scrbook}

% Fix \MakeUppercase
\usepackage{makerobust}
\makeatletter
\MakeRobustCommand\@hangfrom
\newcommand*{\ModMakeUppercase}{%
    \MakeRobustCommand\@svsec
    \MakeUppercase
}
\makeatother

\addtokomafont{part}{\MakeUppercase}
\addtokomafont{chapter}{\MakeUppercase}
\addtokomafont{section}{\ModMakeUppercase}
\addtokomafont{subsection}{\ModMakeUppercase}

% workaround for version 3.15 and 3.16
