Well, I "suppose" git-add could warn you that you are adding an empty
tree (and I'd like if that happened, implicit vs explicit action i.e.
ignoring).
However, I assume the no-empty-tree case was a design decision; hence,
it's been 2.2# versions without such warning.

I doubt it would be considered to be added now.

I believe Taylor is talking about explicitly keeping a directory
empty, that may or may not, in the future, contain files (that will be
tracked) [1].
You are infering that, regardless if there are files or will be added
in the future, you don't want to check anything in.

While [1] is a very niche corner case (and maybe it doesn't make sense
to the most of us, true), there is a "debian-equivalent" behavior
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812223

(I cannot find the definition of this behavior, but you can see an
example usecase)
