The MinGW packaging guidelines have accumulated a bit of historical cruft:

• Describing things present in Fedora 17 which is hardly relevant 10+ years later
• References to a package comparison script that is lost in time and was never actively usd
• Incorrect reference to %{mingw_package_header} adding dependencies
• Pointless versioning of BR deps to ensure existence of macros that have existed for 10+ years
• Ambiguity in description of which files to include
• No mention of newly introduced ucrt64 build target toolchain

As well as undesirable / broken formatting

• Mangled formatting of the big filesystem hierarchy docs as a result of bad auto-conversion from previous docs format
• Huge paragraphs entirely on one line with no breaks, leaving really unclear git diffs
• Pointless line breaks in tables when content easily fits on one short line
• Undesirable suggestion of vertically aligning spec file tags which inevitably become unaligned over time
