More or less. Most patch utilities will be able to discard patch headers (as seen in git patches output). Strictly speaking “diff -p”, as seen on the wiki, isn't portable either. Also, filenames don't determine how the file format will be parsed by the tools. Still, the page was inconsistent indeed, for example we recommended filename format “toolname-patchname-YYYYMMDD-SHORTHASH.diff” for git patches, but “toolname-patchname-YYYYMMDD-SHORTHASH.patch” for patch generation. It's not too much important though.
