Why fast battleships inherited the battlecruiser's role

Why did the Royal Navy not build explicit battlecruiser versions of its later battleships?

Fast battleships such as King George V and Vanguard effectively succeeded the battlecruiser under a more acceptable name.

The answer cautions against reading ship type names as fixed technical categories. After Jutland, the battlecruiser label carried an uncomfortable historical burden even though navies still wanted capital ships combining speed and heavy fighting power. King George V and Vanguard fulfilled much of that role under the safer title of fast battleship. The comparison helps explain how doctrine can persist after the terminology used to describe it changes.
