QubesOS/RUST-Parser roadmap?

[20458'0458'02458'0283'289'4283'0258'305]

Hello,

How much (security-relevant) coding is mitigated from C to RUST in Qubes?

Will be there some C/RUST switch in the QubesOS installation procedures (so that everybody has a free choise)?

Parts of Librsvg was mitigated to RUST under Federico Mena Quintero and in his experience he found, that parser should be the next RUST target, to harden a IT-system.

Is there, or will be a QubesOS/RUST-Parser roadmap?

Kind Regards
