Chaosium's Basic Roleplaying uses their own rewrite of the OGL, which has a less trap-doored section on license updates: https://www.chaosium.com/brp-system-ref

  It also has some really restrictive terms around using otherwise available material. You can't use it for anything derived from "all works related to the Cthulhu Mythos, including those that are otherwise public domain; and all works related to Le Morte d’Arthur." This is of course to protect their own games, but walling off anything related to the primary source for Arthurian legend is awfully broad. Are all knights related to that? Also doesn't use "irrecoverable" so it's got the same potential problem as the OGL does, right now. Hopefully they'll change it. Interestingly Delta Green (a Call of Cthulhu variant) just decided to drop the OGL from their books, which means they're just flat out using a system which is 90% identical to the Call of Cthulhu BRP variant without any license at all. I'm curious how that will go.

    "irrevocable" isn't the 1.0a problem, "authorized" is. BRP OGL specifically rewrites that section (section 10 there) to explicitly make products published from older versions retain the older license - you can sell a product published with an older BRP OGL. The authorization question with Hasbro's OGL is whether 1.0a products lose their license because Hasbro allegedly deauthorizes it in 1.1. Also their license FAQ spells out the Arthurian limits (you can, just not commercially with their system in a BRP OGL product).
