Umbrello C++ const bugs

From the Umbrello CODING-STYLE document at item 43 (line 245 in the one I have,
may not be up-to-date):

" 43.) "const correctness" should be preserved as much as possible.
      Make all getters const."

Question: Has anyone actually tried to do this with the existing Umbrello
sources?

I did, and I had to change about 400 lines of code in just about every file in
the source tree before it was again usable. The problem with const
(in-)correctness is that it is somewhat like cancer: Once it has started in
some code somewhere, it propagates until the entire code base is unusable if
one insists on subsequent code being const-correct.

But I get the impression that for some of the Umbrello code, which has
obviously been around since the very beginning of the app, this was never an
issue. At some point, a well-meaning maintainer decided "Oh yes ... we should
require const-correctness in our coding standards".

I am a great believer in const correctness. So I have another question:

How can we do this? I am posting the document I created with descriptions of
all the function signatures in all the files so that people can try to follow
up on it. But since I am not a regular contributor to the Umbrello project, and
still have issues with Git, etc., I will leave it up to those who can actually
navigate "invent.kde.org" and do something useful here.
