Even though I was able to force a rebuild of the package with the flags enabled (see #7867) and the corresponding docs were uploaded successfully, the package's summary page on Stackage needs some kind of update.
The docs (including the modules behind flags) can be seen here:

Yet the modules behind flags are not listed here:
