Does the stretchability has actually any effect?

You could try the following. (I copied the code of the WordSpace
option an removed the settings for \fontdimen2.). SetStretchSpace
take one or two argument. I'm not sure that you always get something
sensible if you set them to something different then 0.
\documentclass{article}
\usepackage{fontspec}
\ExplSyntaxOn
\makeatletter
\define@key[zf]{options}{SetStretchSpace}{
\fontspec_update_fontid:n {+setstretchspace:#1}
\bool_if:NF \l_fontspec_firsttime_bool {
\_fontspec_parse_setstretchspace:w #1,,\q_stop
}
}
\cs_set:Npn \_fontspec_parse_setstretchspace:w #1,#2,#3 \q_stop {
\tl_if_empty:nTF {#3}
{
\dim_set:Nn \@tempdimb {#1\fontdimen3\zf@basefont}
\dim_set:Nn \@tempdimc {\@tempdimb}
}{
\dim_set:Nn \@tempdimb {#1\fontdimen3\zf@basefont}
\dim_set:Nn \@tempdimc {#2\fontdimen4\zf@basefont}
}
\tl_put_right:Nx \l_fontspec_postadjust_tl {
\fontdimen3\font\the\@tempdimb
\fontdimen4\font\the\@tempdimc
}
}
\ExplSyntaxOff
\makeatother
\setmonofont[SetStretchSpace={0}]{DejaVu Sans Mono}
\begin{document}
\ttfamily
\the\fontdimen2\font,
\the\fontdimen3\font,
\the\fontdimen4\font
\large
\the\fontdimen2\font,

\end{document}
