I don’t think anything about the Wuhan Coronavirus *requires* engineering or purposeful manipulation. As such, it is a technical/political question, not really a pragmatic one.
It could be a totally naturally occurring virus from bats collected in the wild for research purposes that Wuhan researchers had isolated and were studying
One of the top research fellows in the lab was the world leader in collecting bats from all over the world to study how they can simultaneously house multiple strains of highly infectious corona and other viral strains and not fall ill.
Research does not necessarily have focus on the virus itself- research can focus on how the bats have adapted to living with the multiple virus infections without getting sick
