Given that most "open source" apps are a pain in the neck to recompile (if not downright impossible), I don't blame you. It takes a surprising amount of work to make things easy for end users (but it's worth it, IMHO).
I've wondered about bytecode / p-code lately. Usually it's slower, but it's at least neutral. Maybe compiling to bytecode for redistribution then the end users can optionally recompile to native code with localized tools. (No, I don't mean LLVM.)

I disagree with this. I've seen significant slowdown with software emulation (and bugs). For "normal" apps it's okay. But there are a lot of apps which are painfully slow (e.g. DJGPP, but often even 16-bit is slow as molasses). Fast emulation is possible, but few care.
However, MS emulates x86 (and x64?) apps on ARM64 Windows, so it's not a bad idea. (Supposedly they also support DirectX 9-12.)

IBM is one of the biggest businesses in the world and commercially supported DOS for over 20 years. It's not so much times changed: people changed. It's more their personal taste than raw technical requirements.

DOS/NT (predecessor to DOS-C) ran atop 68k processors for a client, right? But it was very limited. Full MS-DOS portability is harder for other architectures (needing some emulation).
