Hm. My first reaction was that it works as expected. If I explictly
require that the *user* gives a value, a *package* default doesn't
make sense and shouldn't replace the user action.
It is also consistent with the other way round:
\documentclass{article}
\usepackage{expl3}
\begin{document}
\ExplSyntaxOn
\keys_define:nn {test}
{
testb .code:n = {#1},
testb .value_forbidden:,
testb .default:n = {xxx}
}
\keys_set:nn {test} {testb}
\end{document}
