That's exactly why those options where removed in the first place. To stop 
everyone from breaking their configuration, then report bogus bugs. Wine 
"official" stand on those type of settings;
1. Wine should detect all options automatically. And adjust them as needed 
(depending on a specific application and/or requested features)
2. If 1. doesn't work - file bug to have Wine fixed.

PS. If you finding yourself needed to add all your custom settings back - 
save them as a .reg file. Then import it in one go using regedit.
