Era 300 - Not quite Sparta

I just purchased a pair of Era 300s to add to my Sonos collection. I can fully understand the reasoning behind the absence of sound from the front-firing speakers when part of a surround setup. What I cannot understand is why Sonos is depriving its customers of enjoying the Era 300's full capabilities when listening to music in FULL mode while still in Surround mode. The only way around this is to remove them from surrounds, lose the Trueplay setting, and use them as a pair, only to have to add them back to the surround setup and re tune Trueplay every time. It's not like they are €40 speakers. Paying a premium price for such a product should leave customers looking forward to more products rather than regretting their purchase.
