Checkbox update for commit 6fabdba9 (deleted the file, but its
tasks.md diff wasn't included in that commit due to a git-add
pathspec issue on the already-git-rm'd path). Marks 4/4.1/4.2 done
and records the two out-of-boundary doc mentions found during
task 4.2's post-deletion review. All 12 tasks / 4 major groups are
now [x] -- the eliminate-frontend-makefile feature is complete.
