The progress reporting is described for -target-download but not mentioned
for load.

OK.  I can see a problem now: if I start GDB normally and use a command like
"interpreter mi -environment-pwd".  Otherwise deprecated_show_load_progress is
presumably only set to mi_load_progress if GDB is invoked with "-i=mi[N]" as
there is currently there is no ability to switch interpreters permanently in
FSF GDB.  Or is the problem more general than that?

When I read the thread I thought it was referring to executing CLI commands
from MI, in which case you presumably would want the MI output.

Perhaps mi_load_progress could just do:

  if (mi_version (uiout) != 0)
    uiout = mi_out_new (mi_version (uiout));
  else
    return;

I don't see how mi_load_progress would run in this case.
