Great! Happy New Year, @JoshuaMoelans.

I want to review the changes needed in the forks line-by-line with you before we merge anything. A considerable amount of C++17 and 20 specifics require changing, and I want to ensure these are clear. We also must find a getsentry home for the mini_chromium fork first (since this is currently hosted on my Github).

@JoshuaMoelans, now that we have reviewed it in detail and have a getsentry fork of mini_chromium, can I ask you to have one last look at the submodule chain to double-check for any stupidities on my part? Thx!

[JoshuaMoelans]

lgtm, the chain seems correct! 🚀
