Background: tools is a library packed full of deprecated code, that has equivalents in sal/ (the system abstraction layer). Of course the sal/ versions are often less usable than the tools/ version, so some API improvements may be required on the way too. tools/tempfiles.hxx defines the TempFile class, which is still used at some random places in the codebase. To find them all: git grep "<tools/tempfile.hxx>" The equivalent class from sal is osl::FileBase::createTempFile.
Having a second look at the code, I don't think it is a great idea to kill this. Not a big win at least.
actually it should be very easy to kill tools TempFile because it has a clone in unotools called utl::TempFile... ...which is not that much better of course but it's an easy win. perhaps something better would make sense in the URE... but currently the createTempFile there is incomplete and difficult to use since it's apparently not even possible to create an osl::File from the oslFileHandle it returns.
