This commit revert some of the changes added in #27735 because wc_get_products and wc_get_orders is not fully compitable with API controller queries. Since we are close to release 4.9, its better to revert and fix them properly then rush a fix. This undones some the performance improvements we acheived in 27735, in favor of more stability, hopefully we will be able to restore this soon.
We are using func_get_arg method to receive argument in a backward compatible way since we cannot modify function signature to add more params even with default params. Earlier I was hoping to use DI to create another child class with modified signature and load it depending upon where we are executing from, however since we had to revert DI, we add this workaround to unblock #27735.
