I think he touched on this a little in a follow-up he did: https://blogs.msdn.microsoft.com/ricom/2016/01/04/64-bit-vis...

My interpretation of the shift from < 32 bits into 32 bits is: before we had do do crazy things to algorithms we used to fit in those address spaces. When we transitioned to 32 bits, we didn't have to do that anymore.

So the question might be are there any surprising workarounds in the code because you're only dealing with 32 bit code where if you had 64 bits you could write some more elegant solution.

It's not exactly what you're asking for, but you'll run into a big one in about two decades.

The only other example I can think of is the general "problem" of large databases. There's just a lot more paging and churn that has to happen in a 32-bit address space. Many NoSQL databases in particular have a memory model of mmap'ing an entire database, which runs into a hard limit on 32-bit address space.
