I think it's a great idea!
I've worked hard to arrive at a stage where I view plugins as simple tools. I can pretty much count the number of plugins I use on two hands (I produce mainly rock/pop). Gone are my days of needing the shiniest new toys to play with. Several companies have catalogs that contain everything I need to produce a record. If these companies made their own hardware/OS/DAW it would only be easier for their own programmers to crank out code, and they wouldn't constantly be playing catch-up to the latest hardware/OS/etc..
I understand not having access to every plugin under the sun is a tough pill to swallow for most, but the more I record/mix I find that less is more.
I'll be the first to admit I'm full of bad ideas, tho!
