[c-nsp] Long life build for 65?

[Christian MacNevin]

Hi,
I've been out of the industry for a little while. Before I left, I remember
that Whitney was definitely going to be a long life build
for the 65, but was only Modular. Did a monolithic long life candidate
emerge? I'm still seeing SXF incrementing. What's the current
feeling on what to use and hopefully avoid the SXF curse of constant feature
integration in supposed rebuilds?
Thanks
Christian
