Realistically this is only an administrative issue. Under the terms of the qualification document, World Rowing will write to the NOCs within the next week to confirm the quotas that have been won at the World Champs - with the "neutral" athletes, that isn't going to be possible. Given the IOC clearly want Russia/Belarus to be in Paris, the quota will not be confirmed until they can figure out the logistics of making that happen.
However if neutral Belarussians are not allowed to attend or decide that the restrictions placed on them are too great so they tell the IOC to F***-Off, then the quota will be reallocated to Bulgaria - but the chances that it will be a while before the issue is resolved.
