Errors when no font is loaded

[doncherry]

\documentclass{article}
\usepackage{fontspec}
%\usepackage{libertine}
%\setmainfont{Junicode}
\usepackage{selnolig}
\begin{document}
kafkaesk
\end{document}

When I’m not loading any font, I get these errors:

! Undefined control sequence.
<argument> \l_fontspec_rawfeatures_sclist 

l.158 ...tFeatureActive{dlig}{\@hdligsettrue}{}}{}

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

Currently, selnolig does not throw an error. However, it does not seem possible to get it to work with the default font. TeX.SX question raised 😇

As I noted in a different comment, an hour ago, the package's low-level code changed in many ways in late 2012 and early 2013, i.e., in the final few months before the package was released to the CTAN and began to be distributed via TeXLive and MikTeX.

Yeah, sure. Time to close this issue. 😇
