From the project

No redundancy = bad design

According to page 7: These LEDs are moisture sensitive, they need to be baked and dried before SMT assembly. Not all PCB fabs have this procedure (eg JLCPCB's economic option), be sure to consult and notify the fab of your choice before mass producing the PCBs, otherwise you may end up with extremely high failure rate. (I learnt it the hard way so you don't have to.)
