> expect to find in modern browser fingerprinting

No. Don't need extensions for that. See how Cloudflare Turnstile does it, recently popped up at https://news.ycombinator.com/item?id=47566865 cause ChatGPT uses it now:

Layer 1: Browser Fingerprint WebGL (8 properties): UNMASKED_VENDOR_WEBGL, UNMASKED_RENDERER_WEBGL, WEBGL_debug_renderer_info, getExtension, getParameter, getContext, canvas, webgl

Screen (8): colorDepth, pixelDepth, width, height, availWidth, availHeight, availLeft, availTop

Hardware (5): hardwareConcurrency, deviceMemory, maxTouchPoints, platform, vendor

Font measurement (4): fontFamily, fontSize, getBoundingClientRect, innerText. Creates a hidden div, sets a font, measures rendered text dimensions, removes the element.

DOM probing (8): createElement, appendChild, removeChild, div, style, position, visibility, ariaHidden

Storage (5): storage, quota, estimate, setItem, usage. Also writes the fingerprint to localStorage under key 6f376b6560133c2c for persistence across page loads.

Scanning for 6000 extensions is anti-competitive, surveillant and immoral.
