This is a bad read of this.
While 45 days is ... huge, the inclusion of pets and friends is almost certainly a result of companies who refuse to let anyone grieve when their friend dies.
As someone who has lost _way too many_ people in the last 18 months and only 1 of them being immediate family, having those others considered not worth mourning according to the company is just repulsive.
If some exceptional edge case comes where someone abuses the system for goldfish, that's worth the cost if I can grieve when my dog of 7 years or my best friend of 25 dies.
