Buidler compilation tasks need to be redesigned to support multiple Solidity versions natively. We want to take this opportunity to gather feedback and ideas from the community and add other improvements.

These are some of the ideas that different members of the community have mentioned:

1. Support multiple Solidity versions
2. Support multiple programming languages
3. Let users set any solc config
4. Per-network solc config
5. Let the users customize the artifact format
6. Make the compilation output overridable
7. Add a quiet compilation mode

I wouldn't focus on how to make this change backward compatible for now, but rather on how to modularize the tasks and how to redesign the compilation config.
