The DC current gain of a transistor is not a very important parameter. It just needs to be sufficient so it doesn't draw too much current from the base bias arrangements. If a designer is foolish enough to make his (or her) design strongly dependent on DC current gain they should rethink their design.
Contrary to a common preconception, a transistor in common emitter mode is voltage controlled. Not current controlled. The base current is simply a nuisance that you have to design around.
