I don't see it as much different from what we have today.
Nowadays I am pretty sure that a bad actor with enough money get their hands on strains of really bad stuff since many labs created those to do research. With enough $$$ I bet you can get their hands on them and then release them.
Perhaps, the only difference I see is that it could give you the possibility to (at least in the beginning) to somewhat target the spread. However, given enough mutations it is very likely you go back to an uncontrolled pandemic and so there is no difference from what someone could achieve today.
Additionally, IMHO, getting the blueprint in how to build your protein and then make it so that existing virus/bacteria can produce it, carry it, ... sounds harder and costlier than bribing someone to get something out of said labs.
