** No IPDL binding generator ({{bug|1379739}})
** No WebIDL binding generator for DOM components (Servo must have something here?)
* Android is currently [https://forge.rust-lang.org/platform-support.html not a Tier 1 platform].
** rillian: "As I understand it, the problem is no one has set up tests on a cloud service, so there's no way for upstream to gate work on Android regressions. Qemu emulation is too slow. There aren't many services with arm support, but there are a couple of new options. If someone does the work of setting something up we should be able to get the Rust team to adopt it."
* Management (landing, merging, etc.) of Shared Gecko/Servo components
** The workflow is annoying and inefficient. Furthermore, permission to land directly on autoland is sometimes needed to fix problems, but few people have that.
** There are continuous integration mismatches.
** Servo CI is potentially under-resourced.
** This is not relevant for Gecko-only Rust components, however.
* Remaining minor crash report issues {{bug|1348896}}
* IDE/symbol lookup support?
