Dear Committee,

I propose to amend the process for introducing new language editions, 
such that GHC always uses the latest language edition by default. In 
particular this would change the default language edition to GHC2024 (it 
currently remains GHC2021):

https://github.com/ghc-proposals/ghc-proposals/pull/632
https://github.com/adamgundry/ghc-proposals/blob/ghc2024-amendment/proposals/0372-ghc-extensions.rst#breaking-changes
https://github.com/adamgundry/ghc-proposals/blob/ghc2024-amendment/proposals/0613-ghc2024.rst#implementation-plan

I'd like to invite Simon Marlow to be the shepherd. (Originally I was 
shepherding this amendment myself, in the hope that it would be a quick 
amendment in time for GHC 9.10, but that was clearly a forlorn hope!)

Please guide us to a conclusion as outlined in
https://github.com/ghc-proposals/ghc-proposals#committee-process

Cheers,

Adam
