In terms of needing such a system to be lightweight and specific: this also implies needing it what is sometimes called “adaptive governance” (i.e. you have to be able to rapidly change your rules when new issues emerge).
For example, there were ambiguities about whether SARS-CoV-2 fell under Australia Group export controls on “SARS-like-coronaviruses” (related journal article)… a more functional system would include triggers for removing export controls (e.g. at a threshold of global transmission, public health needs will likely outweigh biosecurity concerns about pathogen access)
