Re parsing: there's work being done on Wuffs which is meant for decoding data formats safely and efficiently. It's a new language, but it's one that compiles into C code.
It's a Google project, and I wouldn't be surprised if it eventually makes its way into Chrome.
Wuffs is not a Google project; it's a project whose code happens to be owned by Google. Most likely it's some engineer's side project and while I wouldn't be surprised if it was incorporated into a Google project, it's definitely not inevitable. It has probably the same odds as any other well-maintained open source project.
I fully acknowledge that the README says that it's not an official Google product. But rather than debating the exact "Google status" of the project, here's the tracking bug[1] for its integration into Skia (the low level graphics library in Chromium). Here's the tracking bug[2] for its integration into Flutter.
