a821 [1] filed a deletion request for openssl-userver-compatibility [2]: Abandoned duplicated of `core/openssl`. There are no differences between the PKGBUILDs (except 'staticlibs', but for this there is `aur/openssl-static`), and the description says "do not use". It looks like it was a dependency of `aur/userver-community` (same submitter).
