if "current" is a deep object here and contains other objects/arrays, you risk that wherever you are sending this shallow copy will mutate those deeper values and potentially mess things up for the code where "current" came from.
Maybe it's not a situation that comes up often, but it would be fairly hard to debug and guarding yourself against mysterious problems in advance is always neat.
