I was on a call with one of the more senior Walmart (non-Jet) architects about Java and .NET back when I worked on the .NET team. He seemed dismissive of the idea that F# (and .NET) ran perfectly well on Linux, and didn't demonstrate even the slightest curiosity about that. We committed strong support for their workloads, talked about our staffing for that support, talked about how they'd flown me out to New Jersey twice for some in-person feedback and learning sessions, etc. Didn't seem to matter to this person. Where my heart lies aside, I also think it's rather dumb. My understanding of the system talked about in this job post is that it's quite mature and works very well, and my default stance for any rewrite is "don't be dumb, don't do it", and that would apply here.
