Previously mentioned this topic, and now it seems that the first usage multiplier for a certain ecosystem platform has gone live. For some badges, this multiplier increase is indeed quite significant.

Currently, no one has collected all 3 available badges, but based on the data, having both Creator Identity Verification and Gamer Identity Verification badges can boost the multiplier to around 0.5%.

This design is quite interesting; it looks like they are encouraging users to participate in the ecosystem in multiple ways through badge combinations. As more people start stacking badges, there may be some interesting adoption curve changes.
