I don’t really care for Go supporting UUID generation, but UUIDs being a type from the stdlib will be invaluable, if they correctly implement the JSON, Text, database/sql and other standard marshallers/unmarshallers. We seriously need a standard UUID type across the ecosystem, and I’m glad it’s coming.
I did an analysis of Go dependencies[1] a few weeks ago and google/uuid is the 2nd most used dependency in the open source ecosystem, so its inclusion will be very impactful.

I would say the same for dec128. I would love a standard TYPE for dec128, with maybe zero cost std lib to transform it into a mutable uint128 or a zero cost conversion to struct{uint64,int64).
