Let's hope this trend doesn't get a toehold like "kid writing" has here in the US. Young students today are already at a disadvantage because they're not marked wrong for spelling words phonetically rather than correctly. In the younger grades children actually WANT to know the rules for spelling, grammar and pronunciation. By late elementary school, which is when curriculae now stress correct spelling, they're not interested. Adding abbreviations into the mix would make it totally intelligible!
