Right, but I need support for variable expansions with defaults, because
there's no guarantee that $XDG_CACHE_HOME is defined in user
environment. I.e., I need the equivalent of shell ${name:-default}
idiom.

AFAICT that is not supported by Mutt natively. Hence the need of
resorting to shell escaping.

Hope this explains,
