The results look good. Can we get this merged?

[ruben-ayrapetyan]

@rtakacs, @tilmannOSG, binary size increases 190732 -> 191092 with the change. Are causes of the increase clear? Could you, please, describe them briefly?

[tilmannOSG]

@rtakacs Can you please have a closer look?

[rtakacs]

We can close this PR since #791 does this modification.
