Au2 Build options - @aurelia/plugin-conventions

We have a large Au1 project that I’m just starting to migrate to Au2. The project is split into multiple au plugins in a monorepo, using a pnpm workspace and typescript incremental builds across the plugins. We use dumberjs for bundling. We use the tsc directly as gulp-typescript seems dead and doesn’t support incremental build, we’re only using gulp for the bundling step via gulp-dumber.

Looking at the au2 options, there is now plugin-conventions step required and the default dumber template for au2 executes this via plugin-gulp. Because we are using tsc directly, I’m not sure the best way of running this conventions transformation. Can anyone give me any suggestions as to how I might be able to solve this?
