Why battlecruisers lost the scouting role

Why did navies stop using battlecruisers for operational reconnaissance?

Carriers and light cruisers scouted better, while a large capital ship was too visible, too valuable, and too likely to become engaged.

Early concepts could place a battlecruiser ahead of the fleet as a fast reconnaissance ship. Aircraft carriers and light cruisers later searched more widely without exposing such a conspicuous and valuable hull. A battlecruiser sent scouting was also likely to be seen and drawn into a fight rather than merely report what it found. Once treaties limited capital-ship numbers, navies preparing for a decisive battle had even less reason to spend that allowance on a reconnaissance specialist.
