I am disappointed to see this move by an ASF committer [Johann] rather
than working within the consensus process.  But if it's really
temporary, then I suppose it's not the end of the world.

On the other hand, if the patch authors never bring it up to the
standards of the rest of the project, well, then it's a good thing we
didn't commit it under a "commit now, fix later" process.

While it's true -- and unfortunate, mea culpa -- that the rest of us
weren't involved enough at the beginning of the counter design
process, that's not the case any more.

The people most familiar with this patch besides its authors are
myself and Sylvain, and we have said (starting a month ago) that
building on the Clock structure looks like the wrong approach.  That's
a big change to the patch, so it's understandable that this is painful
for the authors.
