No.  vc-region-history's presents a concatenation of diffs.

git-timemachine is more akin to a non-existent
vc-revision-same-window.  It is a minor mode applied to a buffer
visiting a version controlled file.  It renders that buffer readonly
and then allows one to 'scroll' backward and forward over that file's
linear history, always showing a fully reconstructed revision, reusing
a single buffer.

My druthers would be for a vc-browse command that pops a new buffer
containing the most recently committed revision of the subject file.
It would support operations similar to git-timemachine:
* vc-browse-show-previous
* vc-browse-show-next

git-timemachine style refinements could include:
* vc-browse-show-commit
* vc-browse-show-annotation
* vc-browsw-goto-earlier-commit   (regex search)
