Just a stub for issue discussed in triage. Importantly, the device discovery tools.

What's the motivation behind removing the fuchsia support from tools?

[chinmaygarde]

There are already bespoke processes in place for existing Fuchsia workflows and this tools support isn't used all that often and isn't well tested on all host platforms. Specifically stuff like the device discovery tools were causing issues for iOS and Android developers.

Past the device discovery, attaching to any remote Flutter process is now better supported because we are better at custom embedder workflows.

So, a combination of lack of use due to supported alternatives and maintenance burden.

Is this going to break your workflow? If so, chime in because we were not aware of this being a breaking change for anyone. But we could be mistaken and may need to hold and consider alternatives.
