I haven't seen the repairability index yet it sounds very arbitrary and prone to be gamed.

There is no need to micro manage how a device manufacturer designs their products as long as they offset the pollution they create by either paying the local governments to dig more landfills or recycle their own products or send it over to someone who can recycle.

There are still open problems on how to measure the pollution but it's a more flexible approach than a repairability score.
