Bumping the arm64/aarch64 build request.
Many of the problems with fragmentation in the 32-bit arm world have been solved with the 64-bit ports. Given a standard arm machine, running a uefi firmware, these machines are capable of acting like normal PCs and installing a wide variety of OS’s which in turn provide the same developer experience as one gets with x86 machines. Mostly gone are the requirements to hack build processes/etc as these machines are now available as cloud instances at AWS/Packet/etc capable of CI loops/etc rather than one-off hacked raspbian/whatever builds. Put another way, Arm has been working hard to create a consistent and functional ecosystem so that small developers don’t have to.
http://www.worksonarm.com is a good place to start if your looking for developer support (although its oriented towards open source, the people behind it are willing to help port anything).
(Just be warned that many of the small SBC’s aren’t yet SBSA/SBBR complaint so they have many of the traditional arm problems (AKA I don’t imagine a software company like sublime wants to build their own firmware in order to develop their products)).

that was 2013 and I totally agree that maintaining an ARM build is going to take away elsewhere.
