Not an expert but I suspect designing standards which would ensure every single device would work with every single other device under all conditions is very difficult, if possible, and likely to be very expensive. You might be able to test a device with every other device but this is likely to cost way too much and you haven't considered different conditions. Of course, I'm not saying the standards can't be better, perhaps they can...

Coincidentally, I was reading the Jan Telepermit newsletter yesterday and it address this issue and indeed Steve is quite right
http://www.telepermit.co.nz/nl146.html#sec3

Why not quite relevant to this topic, I think this quote sums it up:

"Ideally, every modem would provide identical performance, but this simply does not happen and differences in performance can certainly be expected if a $100 modem is compared directly with a $500 modem.

Above all, most modem suppliers would consider Telecom unreasonable if we were to grant permission to connect only the top performing modem types, especially when the majority of our lines are of only 2 km or less from our exchanges."
