I don't think we ever had a library whose primary value was algorithmic improvement, where the algorithm
was also developed by library author.

For many libraries, algorithms and complexities are implementation details. For this one, its the reason
for the library to exist, and the presented performance charts only demonstrate constant factor difference
with std::sort with old compiler and old CPU. It seems quite fair to ask that the main selling point of a
library is well justified.
