Testnets are not stable and shouldn't be included in the XCM language. They should be able to be specified with `NetworkId::ByGenesis`.

## Summary
|
|
|
|
This RFC aims to remove the `NetworkId`s of `Westend` and `Rococo`, arguing that testnets shouldn't go in the language.
|
|
|
|
## Motivation
|
|
|
|
We've already seen the plans to phase out Rococo and Paseo has appeared.
|
|
Instead of constantly changing the testnets included in the language, we should favor specifying them via their genesis hash,
|
|
using `NetworkId::ByGenesis`.
|
|
|
|
## Stakeholders
|
|
|
|
- Runtime devs
|
|
- Wallets
|
|
- dApps
|
|
|
|
## Explanation
|
|
|
|
Remove `Westend` and `Rococo` from the included `NetworkId`s in the language.
|
|
|
|
## Drawbacks
|
|
|
|
This RFC will make it less convenient to specify a testnet, but not by a large amount.
|
|
|
|
## Testing, Security, and Privacy
|
|
|
|
None.
|
|
|
|
## Performance, Ergonomics, and Compatibility
|
|
|
|
### Performance
|
|
|
|
None.
|
|
|
|
### Ergonomics
|
|
|
|
It will very slightly reduce the ergonomics of testnet developers but improve the stability of the language.
|
|
|
|
### Compatibility
|
|
|
|
`NetworkId::Rococo` and `NetworkId::Westend` can just use `NetworkId::ByGenesis`, as can other testnets.
|
|
|
|
