Empty queries in src/test/bench

The following files are empty:

./src/test/bench/query21
./src/test/bench/query22
./src/test/bench/query24
./src/test/bench/query25

Is that intentional?

(I see they have been that way for 4 years.)

"The LORD is my shepherd; I shall not want. He maketh
me to lie down in green pastures: he leadeth me beside
the still waters, he restoreth my soul...Surely
goodness and mercy shall follow me all the days of my
life; and I will dwell in the house of the LORD for
ever." Psalms 23:1,2,6
