Answering on completed features threads is not possible for normal users like OP. I did that way back then to allow completed feature request to go “silent” and thus clean from questions etc. Also I’d like to agure that this is rather a workaround.
Because it’s not fullfilled:
selected manually when writing an email
added through macros
attached automatically via triggers or rules
The first one yes, somehow, but not convenient when you just look for attachments.
