Is this somewhat common? It makes intuitive sense, but the big 3 or 4 or whatever number it is (IBM, P&Y, etc) consultancies have "use us for everything" as their explicit strategy / part of their sales pitch. So while they might lose customers like you, there is clearly ridiculously large piles of money up for grabs if they diversify their products, rather than remain specialized. And, of course, any sufficiently good specialist is at risk of being acquired by one of these behemoth generalists.
