+# pyliblzma installs an old 'lzma' module that is incompatible with
+# the 'lzma' built-in in Python 3.  As a result, programs written
+# to conditionally import the latter when available (assuming it will
+# have Python 3 API) are broken by its presence.  The suggested
+# replacement is dev-python/backports-lzma that is backported
+# from Python 3.
+#
+# Yum is the only reverse dependency of pyliblzma left (#643312).  Its
+# last release is from 2011, and the current Gentoo snapshot is
+# from 2017.  Upstream git hosting / gitweb is broken and makes it
+# impossible to fetch current sources.  Fedora is apparently replacing
+# it with DNF.
+#
+# Removal in 30 days.  Bug #643308.

 # Obscure package with multiple bugs open.  Blocks removal
 # of dev-libs/dietlibc (#498256) and dev-libs/beecrypt (#666599).
