I'm not against to add it, but it was my understanding that you and Joerg (?)
are working on getting it in a more stable state.
I saw your mail, about the ffs fixes, which looks promising, but I don't know 
about what Joerg is doing.

What about enabling it one or two weeks after your patches made it into -current
and a few more people have a chance to test -current by then?

Hmmm, I had other experience with wapbl in 5.99.7, that forced me to disable
it (pr 40472).
