Right, I remember this change. In Agda.Compiler.MAlonzo.Compiler I wrote
the following:

   -- Note: Some versions of GHC use stderr for progress reports. For
   -- those versions of GHC we don't print any progress information
   -- unless an error is encountered.

There is no support for this at the moment. Another comment (from
Agda.Interaction.GhciTop):

   -- All options (except for the verbosity setting) are reset when a
   -- file is reloaded, including the choice of whether or not to
   -- display implicit arguments.

Furthermore --ghc-flag is not a pragma option.

Feel free to modify the interface.
