Did 1.84 screw over support craft in fleets?

[Shoujo]

Hello, I noticed that the most recent patch mentioned how ships in a fleet would not follow their individual orders. What I'm imagining will happen is that if I say pick wall formation, and send a fleet out, the unarmed and unarmored support craft (repair, construction, supply) would basically become cannon fodder because they'd be forced to stay in formation. If I put weapons on my support craft, then that means the AI will target them. If I don't put weapons on them, then that means that an opponent with half a brain would switch their targeting priorities to best target my support craft, and slow down my fleet.

Leaving them behind with minimal defense means again they'd be a sitting duck. Leaving a significant defense force would mean the main fleet may suffer. Taking them along doesn't seem like much of an option either.

*sigh* I wish the double wall formations could be configured so that support craft would at least stay behind the armed ships.

Am I being worried over nothing, or is this a valid concern?
