Starting a discussion to gather feedback about this feature, so we can move it out of experimental in a future version of Vite. We should also discuss its default value too.

I can't seem to get this to generate any css source maps at all.
my vite.config.js:

build: {
    //...
    sourcemap: true,
    css: {
      devSourcemap: true,
      preprocessorOptions: {
        less: {
          sourceMap: true,
        },
      },
    },

with less installed.

Leaving here a comment that we should wait to stabilize this option. We're working on a new API surface that includes a new dev grouping of config options:

• feat: environment api #16129

Instead of ccs.devSourcemap, this option should probably be called dev.sourcemap: boolean | { js: boolean, css: boolean }
