Yes, that would be a good reason to work towards supporting
application/x-tex rather than application/x-latex, since for TeX there
would be no requirement for there to be a "full document"; for example,
\setbox 0 = \hbox {$x^2 = y^2 + z^2$}\shipout \box 0 would suffice, and
the final \end would be implied.
