It's not just what people are used to, it's what existing software
depends on. What I'm more worried about are shell scripts, such as build
scripts in software packages. They exercise an unknown amount of
behavior out of these commands, and do so in a way that's already been
written and already works, and would be a bit of a pain for third
parties to debug after the fact if the tool behavior changes significantly.

Part of my goal here is to make android a self-hosting development
environment. That implies a certain amount of compatability with
existing linux systems, or at least the standards they implement.

GNU/Linux isn't: Linux=GPLv2, GNU=GPLv3+, they can't share code.
Either it's "mere aggregation", or a license violation.  Pick one.
