No. You can complain about insufficiently documented APIs, or internal APIs that you wish you could use but are not documented, but please do not complain about undocumented APIs that are used by Microsoft applications outside of Windows.

Ever since the monopoly rulings against Microsoft, they have had extremely strict internal controls preventing non-OS code from using undocumented APIs. If a DLL or EXE does not ship on the Windows client install disk, it cannot reference APIs which are not documented in MSDN. Full stop.

You're referencing an API that inadvertently didn't get documented, but everyone knows about it, has blogged about it and lots of articles mentioning to use it? Too bad. Either stop using the API or delay release by 3 months for the next MSDN update.
