I know your question is rhetorical, but worth addressing because it's relevant.

> Why is x86 the primary server platform?

Cheap PC prices plus Linux meant you could deploy Linux for a fraction of what deploying any other Unix (save the *BSD family which shares similar advantages).

Cheap ARM CPUs and reasonably priced, performant ARM development machines pretty much harpoons that big advantage x86 had.

> The issue is that there are always differences that are hard to compare when switching platforms if the one you are developing on isn't the same as the one you are targeting.

Yes and no. We've been developing on MacOS and deploying to Linux for some time. The issues we end up fighting are minimal and we're going from one OS to another. I suspect most of the ARM-x86 issues that haven't already cropped up and been dealt with will be soon.
