[...] I know it's nonsensical, but this was done as a workaround for #827028. You seem to be saying that dpkg won't allow an M-A foreign package to satisfy a :native dependency, even if the package is native. Which would mean we can't both support cross-building with openssl 1.0, and building with openssl 1.1, from the same source package. Please can you allow this 'nonsensical' case so that we are not forced into a choice between two possible build regressions?
