It would be fine, if starting wineserver would be performed by wine on demand itself
I don't know any situation where Wine is used and Wineserver doesn't run. It is needed for basic tasks like registry access and window message passing.
I believe running a single wineserver instance per prefix should be protected against race conditions if you start and stop wineserver and wine processes in quick succession. Although admittedly I haven't looked up the relevant source code.
