We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
RemovedInTTK2Warning seems strange
There is ``RemovedInTTK2Warning`` which apparently was meant to flag feature which will be removed in translate-toolkit 2. However it is already out and that did not happen :-).

Either RemovedInTTK2Warning should be renamed as translate-toolkit 2 has already been released, or the deprecation should be applied.

However it seems that quite a lot of the code seems to rely on that behavior.

--- END ISSUE ---

Below are some code segments, each from a relevant file. One or more of these files may contain bugs.
