It's probably not out of the question, though are there a lot of people out there who want to actually develop on e.g. Android rather than just targeting it?
My laptop is armv7 linux, and not being able to run rustc on it has been annoying. Well, I did find some binary of some old version somewhere, but it's of limited usefulness since it's old, and it didn't come with cargo, which also wants to bootstrap itself from a native binary. The last time I tried it, I couldn't even cross-compile an ARM rustc from x86_64, because the build scripts wanted to run the binary they were building. This is literally the only reason I've been using C and not Rust (which would have been a much more suitable language) for my latest project.
EDIT: Huh. I guess they do have binaries for arm linux now, at least for nightly and beta versions, as of literally two days ago.
Having just acquired a pixel c tablet, I am increasingly looking forward to being able to iterate on my rust projects while being highly mobile. I don't see it as a primary development platform in the near future, but absolutely invaluable as an auxiliary one.
The last time I checked android compiling looked very complicated, tons of steps, tool chain setup for Windows. I hope one day it's as simple as flagging the build for the specified architecture.
