+# TODO: Drop this (along with the host-hunspell mount-control
+# declaration in snapcraft.yaml) later in the future once a
+# reasonable amount of time has passed and nearly all users
+# have an updated version and were migrated to use system-files,
+# and just about no new Ubuntu installations start with a
+# Firefox snap that has the older mount-control interface.
