I'm an exiftool user and photographer that's been using exif datetime to rename files to YYYYMMDD_hhmmss_nn.ext since 2001. I saw it as a great acknowledgement when Google switched to this format for their Camera files in Android. The only thing that differs between my scheme and theirs is the _nn. It normally says _00, but if there's more than one image taken for a second it will go upwards(_01, _02 etc).
