For the first part, it is certainly of interest to some, as a number of folks have collected the existing data. For the second, the issue is probably urgency. The data would need to be collected in situations that are currently overburdened and there are only limited capabilities to do additional testing. Once the situation winds down (as it has in China) I am sure folks will try to collect more data in general and figure out the relevance of co-morbidities. At the same time, folks are actually collecting as much data as they can. And again, often it means more work for medical staff as they need to collect the data, code it appropriately on top of the work they need to do.
As with all research it often boils down to expected impact, available personnel and funding. Though for the latter, there is a lot of money injected into everything COVID-19 related.
