Ok, if that is the only reason, please mention this in the commit message.
That would be enough for me to not wonder about this issue.

But I wonder how you solve this issue if the amount of code behinde your wrappers
grows.

If you have to take them out of line, it would give me a good indication
of the costs involved in the later bodies of these now trivial wrappers,
if you do it right away. 

That way you'll find missing includes and whatnot while converting existing code
to the trivial wrappers.
