One potential solution: - During a session, the first time rust-toolchain encounters a proc macro it must run to analyze, it will first prompt the user and warn them. - If the user accepts the prompt, rust-toolchain will freely run any proc macros until the next session. - If the user rejects the prompt, that analysis will be disabled until the next session. Similar to how VSCode and other apps handle opening links.
