biblatex: \citeauthor should show more names than \textcite (no "et al.")

Question

• I am using \citeauthor from the package biblatex to print the author names of a publication.
• I want that \citeauthor prints ALL names (only be limited by maxbibnames and not by maxcitenames.
• Is there a clean way to do that?
• I am flexible regarding the details (e. g. incl. or excluding the given names).

\documentclass{article}
\usepackage[maxcitenames = 2, maxbibnames = 10]{biblatex}
% See https://ctan.org/tex-archive/macros/latex/contrib/biblatex/doc/examples
\addbibresource{biblatex-examples.bib}
\begin{document}
\begin{description}
\item[cite] \textcite{padhye}
\item[citeauthor] \citeauthor{padhye}: Here, I need the full list (up to 'maxbibnames = 10') of authors as shown in the bibliography.
\end{description}
\printbibliography 
\end{document}

Answer 1

The idea here is the same as in How do I instruct \fullcite to use maxbibnames rather than maxcitenames?. Take the original definition of \citeauthor (ll. 2172-2181 in biblatex.def v3.17) and add a \defcounter{maxnames}{\blx@maxbibnames} to locally set the maxnames counter to its bibliography value.

\documentclass{article}
\usepackage[maxcitenames = 2, maxbibnames = 10]{biblatex}
\makeatletter
\DeclareCiteCommand{\citeauthor}
  {\defcounter{maxnames}{\blx@maxbibnames}%
   \boolfalse{citetracker}%
   \boolfalse{pagetracker}%
   \usebibmacro{prenote}}
  {\ifciteindex
     {\indexnames{labelname}}
     {}%
   \printnames{labelname}}
  {\multicitedelim}
  {\usebibmacro{postnote}}
\makeatother
\addbibresource{biblatex-examples.bib}
\begin{document}
\begin{description}
\item[cite] \textcite{padhye}
\item[citeauthor] \citeauthor{padhye}
\item[cite] \textcite{padhye}
\end{description}
\printbibliography 
\end{document}
