There is no harm, it clearly marks the end of a variable name and
silences shellcheck warnings.
E.g. TMPFILE is set by mktemp which uses the user-controlled TMPDIR
variable. There might be strange people out there who use whitespace
characters in their TMPDIR name making the script break.
Add a comment and ignore the warning where we really do not want quotes.
