Some copyright nitpicks: The GFDL-1.2+ is actually the variant GFDL-NIV-1.2+.
Please rename the license that is currently called "MIT" to "X11", which is the usual name for that license. build-aux/ltmain.sh includes a snippet with "Copyright (C) 2004-2019, 2021 Bootstrap Authors" dual-licensed under Expat and GPL-2+. Please add that info.
