I have a bit different expectations in respect to export predicates. It 
should be possible to express that some content should be exported by 
all backend except the given list. The use case is fallback for backends 
not covered by export snippets:

    @@latex:\textbf{\LaTeX() formatting}@@@@html:<strong>HTML 
formatting</strong>@@@[...]{*for other backends}

Earlier I raised this issue during discussion of @@:...@@ syntax extension:

Another case for backend predicates is whether it should be applicable 
to derived backends or just to explicitly specified ones.
