Flags like --theme and --extend-css don't seem to be used for standalone markdown files IINM, so they don't really need to be included in the dep-info. Of course, impl'ing that isn't worth the complexity, this approach is fine as is imo.

I have tested your patch locally and ran rustdoc test.md --index-page my-index-page.md --emit=dep-info (with the appropriate source files) but my-index-page.md wasn't listed in the resulting dep info (for comparison, --html-after-content did obv work as the tests also confirm); I might've overlooked something tho.
Note that the custom index page isn't properly tracked in "normal mode" either (where the source file is Rust), neither on main nor on your branch AFAICT.

I see.
I notice that write_dep_info is run before the renderer is run. To fix this, I either need to add the file to the source map separately (which can be done the same way --html-before-content and related options are done), or move when the renderer runs.
The less risky option, at least in the short term, is adding the file separately.
