Weight saving and simplicity are both very valid concepts when building a spaceship, but there is another concept which is important: redundancy. A few more thrusters than the minimum needed, and some perhaps running on alternative fuels, might come in handy one day.

BTW, I wonder what are those short black tubes at the engine section.

6 years difference! It's an incredible development that SpaceX has made in recent years! And all this thanks to the passion and the goal in mind! We appreciate it! 👌🏼
Can’t believe it’s been 6 years since our first vertical landing!
Grasshopper flew for the first time on September 21st, 2012 Just shy of seven years.
