What / how to css between multiple options? (docs question)

[kwonoj]

Reading through docs, I could see multiple loader / options are pointing to process css

• https://rspack.dev/guide/features/builtin-lightningcss-loader#builtin-lightningcss-loader
• https://rspack.dev/guide/tech/css#using-style-loader (and others like https://rspack.dev/guide/tech/css#native-css-support)

The current migration I had works, but I came to bit confused to understand what's recommended pattern / path forward if I want to migrate from webpack loaders.

TL:DR, what css options are recommended and what should be used in which cases?

• When should enable lightningcss-loader? Is there an equivalent / similar legacy webpack aims to be replaced?
• When should use webpack's existing loaders (css-loader, style-loader, ...)?
• When should use native css experiments options, and in that case what need to be additionally configured among above
• And other general migration / recommendations?
