Not really, it's mainly to do with getting a measure of how transmissible the virus is in stadiums and also researching how stadium design can be adjusted to minimise that.They describe this as a test event, which implies they are testing it as the model going forward.

Airborne Infection Reduction through Building Operation and Design for SARS-CoV-2 (AIRBODS)
AIRBODS is a joint research programme between Loughborough University, University College London, the University of Cambridge, the University of Nottingham, the University of Sheffield and London South Bank University. AIRBODS is a UKRI-funded project which aims to quantify the risk of transmission of SARS-CoV-2 in buildings, and thereby offer guidance on the ventilation operation and future design of non-domestic buildings.
The team’s role in the Events Research Programme is to collect environmental data around the venue. We will do this by monitoring indoor air quality (measuring and recording CO2 levels, air temperature and relative humidity - moisture content) in the air at different locations around the venue, and relating this to the number of people present and microbiological analysis of surfaces around the venue. This data will be used to determine a Relative Exposure Index. This is not an absolute measure of the risk of transmission, but a measure of exposure relative to a benchmark case.
