Given that there would be no need to file a non publication request for a provisional, I assume the answer has to be yes.
Under Roman numeral II in the link at the bottom, it states:
"For example, a nonpublication request filed with a request under 37 CFR 1.53(c)(3) to convert a provisional application to a nonprovisional application will not be accepted as timely filed because the nonprovisional application would be accorded the original filing date of the provisional application if the request to convert is granted. The nonpublication request must also be included with the application papers. The nonpublication request cannot be filed separately on the same date as the filing date of the application (e.g., the nonpublication request is filed in a different "Express Mail" package than the package that contains the application)..."
Maybe I'm reading it wrong, but it seems to state that filing a non-publication request with provisional papers is sometimes necessary ... ??
