Vaadin 8 Layouts - default for setSpacing changed?!

In looking at the Book of Vaadin for versions 7 and 8 is seems that the default for using spacing in ordered layouts changed from false to true. Is there a global that I can set to return the default to false (as it was for earlier versions) so that I don’t have to parse through each of my UIs?

I guess not, so I sub-ed VerticalLayout and HorizontalLayout, reset setSpacing in the constructors and referred to my subs in all my uis. IMHO Vaadin is way too mature for the development team to be making disruptive changes like this (and changing the default spacing and margin size). I’d be screwed without sed.
