Note, while I appreciate the elegance of not having options that don't make sense for a particular platform note that it will mean that if I'm used to working on say Linux, and I put:
command alias run process launch -A -- in my .lldbinit, then move over to windows and carry my .lldbinit with me, my run command will no longer work. So there's a trade-off between cleanliness and portability here...
