isn't sonar now the only windows-only daw?
Mixcraft & Samplitude/Sequoia, ACID, SAWStudio are still windows-only.
are these daws commonly tested with by the plugin devs?
Why do you ask me? Ask those devs whose plugins are important for your work. 
not asking you particularly, but generally, responding to the comments that sonar's not officially tested with, hence my speculation that maybe it's (not) because it's (not) the only windows-only daw :-)
(fwiw, i personally don't have any particular plugin trubs)
