This sounds similar to the T700, with -701D engines they need to be cooled down by motoring starter to get cooling air through the engine and get TGT indication below 30C, though in this case it is more to prevent compressor stall on startup.
Things can get missed in any system I suppose, even with a message to warn you a task needs to be done, pretty bad that missing this step could cause your engine to fail though.
