You must have forgotten the days where all chargers had a molded cable instead of the USB-A socket that is standard these days, and the plug was different for each and every brand. So each phone came with both a custom cable and a custom charger.
So you have changed your problem from finding one of N charger to finding one of N(N-1) adapters, assuming someone actually built and sold for example a Samsung-to-LG adapter. Not a great improvement.
