If the documentation for a directive (available here at
http://nginx.org/r/sub_filter_types) does not say that the value can
contain variables, then the value probably does not process $variable
content.

Compare with the documentation for this directive - http://nginx.org/r/sub_filter

sub_filter_types does not read variables. If you set the type to the
string "$subfilter_allowed_content_type", sub_filter might take effect. (I
haven't tested, since it is not a useful case, I think.)
