Hide Empty staves - persistence into MusicXml

During my perusal of changes, I found this aspect - Hide Empty Staves.
This is just great, I thought. I can now reproduce the scores I have to transcribe to pass them into my application.
I was quite disappointed to find that this aspect seems in no way to be persisted into a MusicXml export.

I could be done, quite simply according to Michael Good, by adding the following to the first measure to be hidden :

<attributes>
    <staff-details print-object="no"/>
</attributes>

with the following when the measures are to be displayed again :

<attributes>
    <staff-details print-object="yes"/>
</attributes>


Could this be integrated ?
