Nope.... Still the same. You can log off if stuck in mailslot and you'll be outside. Note.... That pertains to Xbox one
Ah, lucky you. They changed it on the PC version a few months back. I had another instance of it a few days ago, so I can confirm it still takes you back to the dock on PC. Downside - no escape. Upside: If you undock, and then remember you needed to do something (e.g. check mission boards, sell cargo, etc.) before undocking, you can menu log/log back in, and you're back in the dock and can do what you forgot.
