+      NOTE(compnerd) Use high compression as this is an extrodinarily large
+      cabinet.  With upstream being amenable to considering decorations for
+      DLL builds, this might be possible to reduce in the future hopefully.
+      In the mean time, burn the CPU cycles to try to claw back the minimal
+      bit of savings to hedge against the constant complaints that the MSIs
+      are too large.
