I expect that

#+BEGIN_VERSE


From fairest creatures we desire increase,
That thereby beauty’s rose might never die,



#+END_VERSE

is exported to

\begin{verse}
From fairest creatures we desire increase,\\
That thereby beauty’s rose might never die,
\end{verse}

and internally at some point it is represented as
"From fairest creatures we desire increase,\nThat thereby beauty’s rose 
might never die,"
without leading and trailing newlines.

I do not see any use case for "\\" at the last line. Perhaps it might 
even cause an org-lint warning. From my point of view, it is preferable 
to require more verbose markup in special cases to make intentions explicit.
