Yeah, we thought we were going to do that with our VAXen. After all, that's
the approach we had used on every previous program. However, there's some
ugly consequences: (a) it runs at cross-purposes with another popular
corporate trend - standardizing on a single (yet evolving) platform to
reduce cost; (b) it makes it even more difficult to attract quality software
engineers to the project; and (c) it assumes that you're also going to be
able to freeze your target architecture (e.g. MIL-STD-1750, MIL-STD-1553...)
which is also no longer realistic.
