Syntax
bool bReplaceReferencesToOldCDOs
Remarks
Indicates whether CDOs should be included in reference replacement. Disabled by default since this can increase search cost, because this effectively means replacement will require us to do a referencer search for at least one instance of every remapped class (i.e. - the CDO). In most cases (e.g. load time), incurring this cost is unnecessary because the CDO is not expected to be referenced outside of its own class type, so we treat it as an opt-in behavior rather than enabling it by default.
Note: This flag is implied to be 'true' if 'OriginalCDO' is non-NULL. In that case, the value of this flag will not be used in order to maintain backwards-compatibility with existing code paths.
