I'd prefer it if the genus names were retained for clarity, but the 'sloppiness' of treating them as species in (for example) surveys of fossil diversity just be acknowledged.

I know the genus doesn't seem to mean anything, but that can be changed, as you said:

And i'd like to add though that when i think of a particular species, i don't think (for example) "Genus: Tyrannosaurus. Species: rex." I think "Species: Tyrannosaurus rex". So eliminating the "concept" of the genus doesn't have to mean changing any names, we could just define "genus" as nothing more than "that extra word we have to make it clearer which animals we mean". To me this seems easier than _effectively_ changing the name of every species in palaeontology.
