I still want to see proper XDG support, not chuck-all-the-files-under-$XDG_CONFIG_HOME which violates XDG and is not compatible with network home directories.

Additionally, there's a number of open issues that all touch the same xmonad core code and really need to be done together, unless we plan to rewrite that code completely for each change. See https://github.com/geekosaur/xmonad.hs/blob/master/new-startup-config for an outline that addresses all of:

• XDG (and proper OS X --- yes, people use xmonad on OS X) support
• sandbox support (cabal and stack)
• a proper fix for the xmonad-on-$PATH issue, plus other mechanisms to work around XDG sessions essentially requiring a full session manager
• more flexibility in order to support e.g. testing configurations (this is not discussed in the above but the design is actually based around working code I've used for that; I still need to work out interactions with the sandbox support)
• handling the xmessage problem (this part is still subject to change, as the current spec is very definitely a hack based around accommodating existing contribs' usage of xmessage instead of rewriting them)

Some of these actually conflict rather badly, notably naïve sandboxes are incompatible with XDG. I don't expect to be able to resolve that, but I can make it possible for the user to resolve it if they need to instead of forcing them into noncompliance.
