Hi René,
[2] On 2019-08-24 I reported the problem to Codeweavers at: https://www.codeweavers.com/support/tickets/browse/?ticket_id=1230834 The problem was confirmed 2 days later, but no solution available. I asked for information about sponsored development to no avail.
It looks like we screwed up; we helped you with the initial conversation, but then your follow on question was ignored. That looks to be something wrong with our internal process we're going to try to fix. (Believe me, we don't ignore it when people ask to sponsor work on Wine, really, we don't <grin>).
I've alerted James Ramey, our President, who handles sales questions, and hopefully he will reach out to you shortly.
Cheers,
Jeremy White CEO CodeWeavers
