[css3-values] recommendation for pixel units

In section 5.2, with regard to lower-resolution devices, and devices with 
unusual viewing distances (which I assume would include most mobile 
devices), it is recommended that the pixel unit refer to the whole number of 
device pixels that best approximates the reference pixel.

I take that to mean it is recommending that the device-pixel-ratio should 
always be a whole number. Am I reading that correctly?

If so, is this perhaps worth reconsidering, given that it's not uncommon 
these days for mobile devices to default to a device-pixel-ratio of 1.5 or 
0.75?

I realise this text has been in the spec since the beginning of time, but if 
implementers don't think it makes sense anymore, and are just going to 
ignore it, is there any point in continuing to make the recommendation?

Regards
James
