The bottom line is the growth is only temporary. Currently it's nothing other then reshuffling of airframes. (Who can do it for cheaper while able to staff it?) If you're lucky and hit a sweet spot, you're going to upgrade quickly and enjoy senior line holder's lifestyle, if not - endless misery of reserve. I was unlucky in my first regional. Very lucky in my current one. Still trying my hardest to leave as quickly as possible, as I hope the regionals will shrink and die all together (although I realize the latter may be just wishful thinking on my side).
