We don't know how application users are using this.
The following is some theoretical example, that I'm quite sure could be used
in some real world applications:
QFileInfo embeddedFile(":/foo/data.xml"); // fallback downloaded in the
ancient past
QFileInfo systemfile("/usr/share/foo/data.xml");
if (systemfile.lastModified() > embeddedFile.lastModified())
{
data = readFromFile(systemFile);
}
else
{
data = readFromFile(embeddedFile);
}
If S_D_E gets used, rather than the data.xml modified date in the source, this
will end up using the wrong file if S_D_E is newer than the system copy of the
file.
This is not a unused databit, but a fully available piece of metadata for the
files.
