As said in my initial mail, the point is that it has been found nine
years after that removing the DT_HASH table makes Debian and a few other
distribution incompatible with the Generic System V Application Binary
Interface [1].
This has been found to break the "Easy Anti-Cheat" system [2] on
distributions that have their toolchain differing from the upstream
default --hash-style=both, as since version 2.36 glibc uses the system
defaults instead of enforcing it. Distributions which use the toolchain
default have been unaffected.
With this new data points, we should at least think again about the
change that was done nine years ago, and see if it is still the correct
one.
