While I agree with your general idea my lists are quite different.
I would move Zig (innovates a lot in language and compiler design) and JMAP (IMAP is horrible and needs to be replaced) up and CMake and Bazel down (I count them the same as Meson). I would say the jury is still out on Google's tweak and on seL4.
Things that seem potentially worth it to me:
* seL4
* Google's SQL syntax tweak
* Rust
* GraalVM
* systemd
* Tree sitter
* LSP
* CMake
* Bazel
These all get you a step change improvement in comprehensibility, safety, or something else important.
Things that seem like more churn than they're worth:
* Noise protocol (relative to TLS)
* JMAP (compared to good old IMAP)
* Nim/Zig/etc.
* Wayland (fait accompli now, but still)
* Varlink
* Fish shell
* YAML/TOML
* Sq?
* Meson
I wish we, as an industry, invested more in improving existing technologies instead of continually abandoning and replacing working solutions.
