Is it worth the effort to write a "X should switch to Rust" post that ends with "but I personally don't have the appetite to do it"?

Migrations of this size aren't not done because they're technically bad ideas, but exactly because they're expensive, messy, and few people have the appetite or funding to do it. Proposing a solution to that is more interesting that just saying "switch to Rust!".

Also, I don't know much Rust (still on my PL bucket list), but usually when I dive into a more detailed analysis of such a migration the most relevant parts are around how much unsafe code will be required and whether or not integrating with the existing codebase has to be fine-grained or can be done in larger modules like Rust recommends.

I would naively guess that a VM would have lots of unsafe code. Are there any investigations on whether the recent vulnerabilities would have migrated to safe or unsafe code?

edit: mea culpa. I didn't read the second to last-paragraph closely enough, which at least proposes a modularized way of doing this with device emulation being written in Rust in separate modules.
