The Sync360 perspective

More efficient compilation can improve development cycles in large codebases. Migration decisions still need to account for the toolchain: language plugins, frameworks and editor integrations may support changes at different times.

A practical next step

Measure the current project before comparing versions. Check support in each important tool and adopt the change separately, with type checking and a reproducible build.
