Well, technically that's something that should be something handled by the
application, and not by Wine :P

If I understood correctly, the access violation isn't going to be received by
the Windows application. Instead, this will crash Wine due to the access
violation, or not?

Well, Wine doesn't even launch without that change, and considering that Apple
may not change that, leaving those as the real parameters for macOS, this may
become more than a temporary hack :P

Also, if the Windows application fails to create the thread, it may find a way
to handle it if it was properly programmed. If Wine receives an access
violation, there is no way that this should be properly handled in order to
proceed using the application, or I misunderstood the consequences of the
access violation?
