Based on https://www.d12frosted.io/posts/2025-11-26-emacs-widget-library this sounds like a library which could potentially improve the ability of everyone to build things with widgets.
Planning to host on MELPA and accept arbitrary contributions restricts that utility (all but ensuring that future libraries included in Emacs itself can never benefit from it). If it goes to GNU ELPA instead, then one day it could be part of Emacs, and the out-of-the-box support for developing with widgets could be improved.
As someone who's done some head-bashing against the widget library in my time (if nothing remotely on this scale), the idea of a well-documented easy-to-work-with widget library built into Emacs sounds amazing, so please do consider keeping that door open. I assume that you wish this kind of library had already been part of Emacs before you'd needed it, and this could be an opportunity to at least make that true for other people.
