From 3de6ed6dc0f3fa1617c876686b62f92eb149c9af Mon Sep 17 00:00:00 2001 From: Tim Ruffing Date: Wed, 9 Jul 2025 09:12:49 +0200 Subject: [PATCH] bip3: Don't require omitting unacceptable licenses I think that requirement is not helpful. I don't think hat including additional licenses will be overwhelming to the reader. If anything, it will obfuscates the actual licensing conditions.
