This is a legitimate question: Has tagline mode obsoleted either
explicit and/or implicit modes?

I think the answer is "no", but the contexts in which explicit and
implicit are the right choice have become pretty darn narrow.

explicit _enforces_ that no internal ids be used, and that no name-based
ids be used.

implicit _enforces_ that no name-based ids be used.

So only when it is a priority to explicitly disallow those things for a
tree's lifetime should those modes be used.  Only a _more_ experienced
arch user would know when they want to rule certain kinds of
functionality out, so as a rule-of-thumb you'd typically want to use the
mode which provides the most options: tagline.
