We used to have a Mono package. It was introduced on August 8 2016 by commit 763b3d50b6249b43fceda51445bbeb1f5f5fd7d0, at Mono version 4.4.1.0, but it was later discovered in April of 2022 that the release tarball that it was built from included prebuilt binaries. Further research revealed that these binaries were not optional. Due to this, a decision was made to remove the Mono package, carried out on September 1, 2022.

We now once again have a Mono package, due to a patch series I submitted on November 29, which after some revisions was committed on December 22. This patch series introduced a full, 17-mono-package sequence that takes us from a mono-1.2.6 built fully from source to mono-6.12.0 built fully from source, using only packages that already have full bootstrap paths. I make no promise that this is the shortest or most optimal path, but it exists and I have verified it works.

As I've spent what is probably an unreasonable amount of time working toward this, I thought I'd share some of my thoughts, experiences, and commentary. Sorry in advance if it gets a bit rambly or lecture-ish.
