Yes, I would.
And it is my belief that is exactly what Trimble intends to do. Let Sketchup remain the un-bloated jewel that it is and offer plugins for the various industries served such as engineering, architectural, construction, game design, etc...
I don't use Sketchup professionally but that is my goal. For many years I worked as a Production Superintendent in Paper Mills. Until discovering Sketchup I created training materials with Visio and Excel to train the production workforce. Effective but not efficient. And certainly not eye candy. Paper Mills have hundreds of pumps, motors, valves, rolls, vessels, instrumentation, and miles of piping twisting in every angle imaginable.
Thanks to the ruby plugin guys here I can create a realistic 3d drawing of a process that knocks the socks off of people in the industry I've shown them to. But it's a slow process. To do it professionally I would need a professional plugin with an extensive library of components and materials. To create such a plugin would be very expensive I would imagine. This is where Trimble comes in.
