Reason for that is whidbey, which needs to pass :nrepl-context to REPLy to work correctly. Here is the link to IRC chat discussing this problem. It's desirable to have some way of doing that from .profile.boot. :)
Examine boot's source code to understand how it currently launches REPLy. Look for where options are passed and identify where `:nrepl context` could be injected. Check the linked IRC chat and the whidbey library for context on the required configuration. Review any existing discussions or attempts in the comments to see if there were proposed solutions or blockers.
