Hi @erin.l
Yes; we were impressed when we first saw it. Hence the addition to the Data Quality Report 
The general policy for correction of previously acquired images is to wait for a reprocessing of the whole archive, with any information on the issue - and its potential remediation by the User community - added to the relevant Level (L1C or L2A) Data Quality Report. It will also be raised as an Anomaly, and included in the Anomaly Database.
As noted by @marpet the feature you have identified is being discussed by the expertise at the S2 QWG, and I would expect an outcome of their analysis in the near future.
Cheers
