A few months ago, the Silverpop export kept breaking because the file was too big (see T92537). Adam suggested we remove the time zone data from the export to reduce the size/speed, and I ran with the idea and sent him a long list of field data I thought we didn't need.

Now that I've learned that Silverpop data is more accurately deduped than Civi, I would love to have the data for the following fields included in the export once more:

is_2006_donor
is_2007_donor
is_2008_donor
is_2009_donor
is_2010_donor
is_2011_donor
is_2012_donor
is_2013_donor
is_2014_donor

Would adding this data back in cause the export to fail as it was failing before? There are still 3 leftover fields worth of data removed as a result of T92537, so I'm hoping that will be enough to keep the export working.
