 - concern: this change may communicate the wrong idea to Cadence users. Although from the protocol perspective randomness is no longer "unsafe", Cadence users will probably not consider it to be such. As far as they are concerned, the randomness (used naively) is still "unsafe" because it is still exploitable by a transaction that reverts to post-select a favorable result. Changing the name of the function to remove the unsafe prefix would suggest to developers that the function is "safe" in the sense that it is immune to this exploit, which it's not. Users can use certain patterns to make their randomness truly safe, but they need to structure their code in a specific way for this to work. The worry is that developers won't realize they need to do this without the built-in warning that a name like unsafeRandom provides. It's preferred to have the name indicate that the user needs to do something additional beyond just calling the function to get a random number; something like revertibleRandom, for example.
 
-- possible concern answer: 
- - Although any transaction with a random call can be reverted, some applications require randomness and have no incentive in reverting the result. Flow-core contracts for instance use randomness without reverting risks. A well-respected dapp also (assigning random NFTs for example) wouldn't want to add a reverting logic to their contract. For these applications, the new exposed randomness is considered safe. Adding `unsafe` would mean there is something wrong with the contract while there isn't.
- - Result abortion is an inherent property of atomic smart-contract platforms, rather than a property of specific functions like randomness. The non-safety comes from the natural language property rather than the randomness itself. We can argue that any logic written with Cadence is revertible, while the prefix `unsafe` or `revertible` is not added for other Cadence functions. Developers should be aware that a state change in a transaction is revertible, not only when it calls randomness (a deterministic game transaction can abort if the player isn't happy with the result for instance).
- - A language should try to provide as-safe-as-possible tools, but it can't guarantee that any program written in that language is totally safe. There is always some responsibility that falls on the language developer. It is possible to write very unsafe contracts and Cadence can't prevent it (using the cryptography functions as an example).
