Because it is never really clear if it is monotypic or not.

For example, you might say _Baryonyx_ is monotypic, but others might consider
it to have two or even three species (_tenerensis_ and maybe _lapparenti_).
There are thousands of other examples (_Triceratops_? _Gorilla_?
_Pterodactylus_? _Tyrannosaurus_? etc.)

You can't objectively say that a genus is monotypic, so this cannot be a
straightforward method for conversion.
