Hi,
While this breakage is apparently not going to be reverted, the users
deserve to know what they are getting into, to avoid hard to track
bugs and misbehavior.
To me this would be worth mentioning on its own in addition to the
note I added to the "deprecation" entry, but repetition is not ideal
and I can see push back on that too, so I'd rather have it listed
just once than not at all.
Thanks,
Guillem

Subject: [PATCH] issues.dbk: Add breakage from merged-/usr-via-aliased-dirs
While this breakage is apparently not going to be reverted, the users
deserve to know what they are getting into, to avoid hard to track
bugs and misbehavior. In particular dpkg has *never* supported this
layout.

+ Take into account that this layout has never been supported by
+ the dpkg suite and breaks several of its core assumptions. Included
+ among these are: not being able to notice file conflicts thus

+ failing to apply stat-overrides, missed trigger activations, failing
+ to find pathnames on search queries, etc.
