Even the word bioweapon is not accurate to describe a deadly (or harmful) biological agent. A weapon usually means that there is a source of deadly force, and a target. The source doesn't want to be hit by the same weapon it uses to hit others.

This is vastly difficult to achieve using biology. Any organism on the planet has it's own agency, and it will hit anything to reproduce and eat. In addition this is not limited to toxicology and releasing toxins, because the agent can just eat tissue.

For example phosphorus has been used in chemical warfare, but even that cannot be described 100% as a weapon. The phosphorus gas can hit people who released it the same as everyone else, it just depends on the wind.

Right now, on everyone palms, there are thousands of organisms which create electricity, eat wood and kill animals. Given that the palms are washed, that number is reduced to some thousand different species. If the palms are not washed the last 24 hours, that number shoots up to hundred thousand different species, even millions.

I do not see any difficulty for someone to enhance a harmful agent and make it deadly, using just regular computation and not even A.I.. However the person who facilitated this, will be a target too.
