A few other bad things about that design. 

1. It replaces a single literal with two triples and a blank node, or else requires inventing a URI. For users who routinely tag text with languages, this is a real burden.

2. It allows pathological RDF such as 
[ a rdf:LingExp; rdf:lang "en", rdf:lang "fr" ]

3. It allows missing information, such as 
[ a rdf:LingExp; rdf:value "chat" ]
[ b rdf:LIngExp; rdf:lang "en" ]

I'm sure I can think of some more by tomorrow.
