I just received the moderation privilege and reviewed this new answer to an old thread as not adding anything to the accepted answer, hence, not worth the resurrection.
What stumbles me though is the comment I got from @jules, stating that it is worthwhile to keep such an answer, since it provides a summary of the lengthy and detailled original answer.
Is this view shared by the community? I always had the impression that thorough, backed and deeply insightful answers are what we are after - even (or especially) if that means you have to read a page of text. The accepted answer in particular is well structured and making use of section headers even. It certainly isn't on the too long list for me either.
Note that I do understand the value of a TL;DR in the accepted answer and I would welcome that. I am just not convinced, that having another answer, which is merely a summary of an existing answer, is worthwhile - or is it?
