and to not be so easy, in fact it is much more hard to recognize if it is set to true as it uses
 https://github.com/openSUSE/libzypp/blob/a01c326e0dfff465a67d101edff1e782485896ca/zypp/ZConfig.cc#L407 which is https://github.com/openSUSE/libzypp/blob/a01c326e0dfff465a67d101edff1e782485896ca/zypp/base/String.h#L333 and because default is true, it use this code - https://github.com/openSUSE/libzypp/blob/a01c326e0dfff465a67d101edff1e782485896ca/zypp/base/String.cc#L81

so to be really correct you need to have similar code here to decide what was original code.
