[Mono-devel-list] DataView, its very weird history and its future

while investigating DataView.cs and bugs related to it I found the history of
this file to be a little weird.
First a bit of background: I work for a company that works on an industry
project (GUI for an industrial laser) which will run on Portable .NET (aka
dotGNU). As you might know or not, dotGNU repackages and uses a part of
Mono's class library as "ml-pnet". Among other classes, the complete
System.Data namespace from Mono is repackaged.
We then found a bug in Mono's DataView back in fall/winter 2004, which I fixed
and posted a patch. A few weeks ago we hit another bug with ml-pnet 0.7.0
(more on that later), I checked out the current Mono SubVersion trunk, found
the same source as back in fall/winter 2004 and fixed the very same bug. Now
it turned out that the patch doesn't apply to the DataView in ml-pnet 0.7.0
as that is a completely different implementation.
While investigating this I found this weird history of this file (ISO dates):
2004-11-11: Implementation A: I fixed a bug, posted the patch.
2004-11-30: I reposted the patch
2004-12-01: Miguel de Icaza commits the patch (r36917)
2005-02-01: Implementation B: Atsushi Enomoto "mostly reimplemented" DataView
2005-05-11: dotGNU released 0.7.0, including Mono's DataView.cs
(implementation B from Atsushi Enomoto, I don't know which SubVersion
2005-05-16: Implementation A: Konstantin Triger overwrites DataView.cs while
"merging the Mainsoft branch to the trunk" with a version that pre-dates
2004-12-01 (i.e. over half a year old), completely reverting Atsushis
2005-07-06: I fixed the very same bug back from 2004-11-11 and posted the
patch. It wasn't a applied since Konstantin was concerned that there is a
"deeper problem" with DataView.
2005-07-14: Since I noticed my patch didn't go to trunk and I reposted my
So my question about the future of DataView: which implementation will be
used ? Will implementation A be continued to be used in the future or will
there be a revert to implementation B (the one from Atsushi Enomoto) ? E.g.,
do I need to bother fixing the bug in implementation B or not ;-)
