The wind seems to be blowing in the direction of removing the
term "bounce" from 2821bis. Different people have different

that there is value in leaving it in.
My perception of the issue is that 2821 doesn't make a clear distinction
between SMTP-time 5xy rejections and messages that are accepted but
subsequently turn out to be undeliberable. Many people use the words
"reject" and "bounce" to encapsulate this distinction, but the words must
be clearly defined and alternative meanings called out as being not the
ones that are intended - cf. the discussion of "forwarding" in 2822.
Perhaps it would be better to use another term instead of "bounce", but I
think that's a minor editorial choice.
