-file-exec-and-symbols is really just the `file' command:

In mi-cmds.c:

  { "file-exec-and-symbols", { "file", 1 }, NULL, NULL },

so it's not restricted to MI.

I don't really use either but maybe it would be inconvenient to have all
the breakpoints cleared, if you wanted to switch to another version of the
same program, say.  It's easier to delete then all manually, just with `delete'
than it is to add them back again.

Perhaps it could be a GDB option.
