From the very beginning of his work on his proofread extension, he tried to exclude everybody he personal doesn't like. Especially IP's he dislikes and treats them the same way as vandals.
There has been at least 3 major updates of his extension, every time he found new ways to discourage people to work with his extension and to complicate the work of author. 
Every time we had big discussion with him after his buggy changes and must find ways to get around his blocking methods. We have a lot of texts (thousands of pages) proofread two times before his extension was developed. We try to convert most of them to the proofread extension. But even Administrators are not capable of setting a 2 times proofread text to the ready state. When we begged him to assist us with this problem he wasn't willing to,  we found away around his restriction. Now there is an update and we have the same problems again,
an this not by an accident. Because when he sees that we find solutions in the js part which is configurable, he moves more and more of his SILLY IDEAS into parts of the code we can't change.
There has been a lot of experiments to get a common working interface with ThomasV but he is not willing to cooperate. In my opinion it would be very easy, to incorporate parameters, to give the project the chance to implement their community consensus of for example IP editing (including second proofreading), setting completed pages to the ready state, ...
And to Brigitte SB
It's not so easy to call take another developer if this one is not willing to cooperate. 
Would it be accepted that there are two different (but extremely similar) pr extensions, active on all wiki's? 
And I don't think that ThomasV is willing to accept any consensus which is not according to his way of thinking.
Have a look at the other ws. Has there been any question of ThomasV what the consensus in this ws is - or is there
only his dictate!
Have a look here. https://bugzilla.wikimedia.org/show_bug.cgi?id=20812
