All necessary newlines are explicitly defined in skeletons,
e.g. a block-like div:
(define-skeleton html-div
"HTML div tag."
nil
"<div>" > \n _ \n "</div>" >)
where ‘>’ at the end inserts a newline too and indents.
But non-block tags are defined without newlines, e.g.:
(define-skeleton html-span
"HTML span tag."
nil
"<span>" > _ "</span>")
and skeleton-end-newline inserts an unrequested newline.

Given the examples above, I don't know what the default value should it have,
maybe nil? For example, 'texinfo-mode' does this:
;; Prevent skeleton.el from adding a newline to each inserted
;; skeleton. Those which do want a newline do that explicitly in
;; their define-skeleton form.
(setq-local skeleton-end-newline nil)
