This appears to be the standard response whenever the suggestion of Fronts is raised. To be fair, it doest really need a human meteorologist to identify the frontal zones of warm and cold air masses. Another feature that has been frequently requested is for the display of "500-1000 hPa thickness isolines" which is available from ECMWF. With this data, the location of frontal zones can then be computed.

From the ECMWF website:
500-1000 hPa thickness is a measure of the mean temperature of a column of the atmosphere between these pressure levels and can be used to distinguish between warm and cold air masses and to indicate frontal zones (i.e. areas of large temperature gradient, where the thickness values are more closely packed together). Roughly, 500-1000 hPa thicknesses below about 528 dam imply air coming from polar regions and thicknesses above 564 dam imply air coming from tropical areas.
