Overview#

SHOULD NOT or the phrase "NOT RECOMMENDED" (RFC 2119), which are Case-sensitive (RFC 8174) mean that there may exist valid reasons in particular circumstances when the particular behavior is acceptable or even useful, but the full implications should be understood and the case carefully weighed before implementing any behavior described with this label.

We may use SHOULD NOT in other contexts but we are implying the same interpretation as a Best Current Practice
