Here quotes of Lukas response from linked PR

The first case

Also note that if a plugin just wants to read options, it should NOT use the options hook because other plugins can still mutate options at that point. If you just want to read, always use buildStart which receives the final options used by Rollup.

The second case

The point is that when Rollup cannot match the export signature of an entry chunk because it needs to add additional exports, it will create a facade chunk that reexports exactly those exports that the original entry point exposed. A facade chunk will have its chunk.modules empty because it does not contain the code of any module, it just contains reexports.
