Comment (by spacedmonkey):

 I have highlight wp_render_layout_support_flag as a possible issue.

 Here is data from different themes and WP versions.

 The data doesn't paint a clear picture. In some cases it faster and others
 much slower.

 The most worrying thing here, is that the function time in TT4, where the
 function is called less but is much more function server time.

 = TT4 theme
 || Version || Function time || Times called || Total server time ||
 || WP 6.3 - TT4 ||  11.8 ms || 310 || 153ms ||
 || WP 6.4 beta 2 - TT4 || 18.1ms || 220 ||  174ms ||

 = TT3 theme

 || WP 6.3 - TT3 ||  4.8 ms || 452 || 151ms ||
