For suppliers, it's a valid question, and it gets more valid every year as the cost of doing business with big B spirals. Thing is, it's just so much damn money up front, that the guys up in Mahogany Row don't really care about follow-on costs, like having to support Boeing staff who don't know what a scroll wheel on a mouse does. Now, though, with (another!) active investigation, possibly one where Boeing loses their in-house DERs . . whew, who knows.
From the DoD perspective? It's not really possible for DoD to offload Boeing. The old airframes - F-15, F-18, 7X7 derivatives of all flavors - are the workhorses of US jet aviation . . or they are perceived to be the workhorses, in any case.
Ah, "perceived" . . there's a huge, ginormous other subject here, and that is the subject of a peacetime military. Specifically, whether the metrics we optimize for in peacetime have any bearing whatsoever when it comes to a hot war with a peer. History says, "nope!". Tech and metrics optimized in peacetime buildups almost never have decisive roles in major conflicts, for somewhat obvious reasons: the enemy sees it coming. Everyone's got countermeasures ready to go before shooting starts.
The victor - the technological victor, which doesn't necessarily correlate with the winner - is the one that adjusts fastest to combat experience. That industrial agility is really the thing that needs to be optimized. Trade offs of course are aplenty here; if you adjust hardware too fast, you damage your production capacity and your logistics. Case in point: the US in WW2 were probably one of the slowest-adjusting of the Powers, technologically speaking, but none of that mattered a good god damn when US industrial capacity was greater than the rest of the planet combined. Combining capacity/readiness with agility is the magic bullet. When historians say the T-34 was the most effective armored fighting vehicle of WW2, that's what they're talking about. It obviously wasn't the best, or even a good fighting platform, but it matched Soviet industrial capability to a T while effectively countering the enemy. It was the best design for the system it was part of. Internet people get in terrible screaming matches about this, not realizing that mil historians evaluate systems, not hunks of iron.
Anyway, I'm rambling now. Short answer, yes. Tons.
