SHOULD or the adjective "RECOMMENDED" (RFC 2119), which are Case-sensitive (RFC 8174) mean that there may exist valid reasons in particular circumstances to ignore a particular item, but the full implications must be understood and carefully weighed before choosing a different course. RFC 2119

We may use SHOULD in other contexts but we are implying the same interpretation as a Best Current Practice
