Why the package does not apply the arabicfont for including macros?

[javadr]

As I mentioned in this question, I was expected to get the correct font when I used some macros like \footnote or \marginpar in arab environment like the way xepersian did. But your great package did not apply the \arabicfont to the macros included in. See the following MWE.

\documentclass{article}
\usepackage{arabxetex} 
\usepackage[showframe]{geometry}

\begin{document}

\begin{arab}[utf]
سلام علیکم \footnote{سلام}
\marginpar{++سلام علیکم++}
\marginpar{++Hello++}
\end{arab}

\end{document}

Will the package support this feature in the future?
