Visual Studio Code has a set of web components designed for writing custom extension UIs that fit with the core VSCode UI - https://github.com/microsoft/vscode-webview-ui-toolkit https://github.com/microsoft/vscode-webview-ui-toolkit - and explicitly mentions that being usable in multiple frameworks is one of the reasons for choosing web components as an implementation tech. It ships React components that act as adaptors for them out of the box (and has examples with other frameworks as well - see https://github.com/microsoft/vscode-webview-ui-toolkit-samples/tree/main/frameworks https://github.com/microsoft/vscode-webview-ui-toolkit-sampl...). Adobe maintains https://github.com/adobe/lit-mobx https://github.com/adobe/lit-mobx which is thee current usual way to write https://lit.dev https://lit.dev components that use https://mobx.js.org https://mobx.js.org for state management. So that's two noticeable Enterprise usages even if they don't seem to show up on HN much.
