I do agree, that P&G are quality. But the situation is slightly different. No moving parts, just two contacts. Current plug is feasible in its use. It may also be good though that the plug is a fuse, the breaking part. When the bass top breaks because of the good locking contact, instrument builders should make the instrument such that they could withstand the pulling when someone walks to the cable etc.
To the original point, I see nothing special in this so called "new" jack. As @Hellzerosuggested, use a stereo jack if in need.
