The output for createIndexes used to look like this before removing MMAPv1:
"inprog" : [
{
"host" : "delphi:28022",
"desc" : "repl index builder 1",
"active" : true,
"currentOpTime" : "2018-08-20T08:31:38.210-0400",

It is basically only intelligible because of the ns field value of "<db>.system.indexes", and that's only to engineers, not users.
After SERVER-36015, it looks like this:
{
"inprog" : [
{
"host" : "delphi:28022",
"desc" : "repl index builder 1",
"active" : true,
"currentOpTime" : "2018-08-20T10:29:38.499-0400",
"opid" : 223,
"op" : "none",
"ns" : "",
"command" : {
"v" : 2,
"key" : {
"x" : 1
},
"name" : "x_1",
"background" : true,
"ns" : "test.index_bigkeys_downgrade_during_index_build"
},
"msg" : "Index Build (background) Index Build (background): 0/10 0%",
"progress" : {

This entry should say "createIndexes" somewhere. The code starting point to investigate how currentOp puts this entry together – and thus where to put the code to improve it – is here: I tracked that code starting from here, but I didn't go any further.
