Well I have a response¹ from someone in the wx-dev group saying that the
missing GTK constructor "is
available in 2.9.2 but chances of this being backported to 2.8 are slim".
I don't know how people would feel about modifying wxcore to use a
constructor which is implemented for 2.8 with GTK?
Dave,

It simply wasn't implemented initially. It was added since then and is
available in 2.9.2 but chances of this being backported to 2.8 are slim.
