I found this web page which describes in detail a browser plugin that exposes Wacom tablet features such as pressure sensitivity in JavaScript. Unfortunately, the download link is dead. Does this product exist?

It's true that the plugin itself is contained in the driver.

plugin file is included in Driver Installer.
If you extract Wacom Pentablet driver installer for Windows (this is executable zip archive), you can find TabletPlugins\fbWTPInstall_x86.exe (and fbWTPInstall_x64.exe).
This file is "Wacom Tablet Plugin installer for Netscape Browsers". So, execute it, then available Web browser plugin demos.
Pressure sensitivity is now exposed by the browser's Pointer Events API for all supported tablets (not just Wacom). Pointer events such as onpointermove will contain a "pressure" field that ranges between 0.0 and 1.0.
Pointer Events are supported by Chrome, Firefox, Internet Explorer (10+), Microsoft Edge and Safari (13+) on macOS and Windows 8+ (Windows 7 doesn't provide pressure information). See:
