It appears that more modules are being compiled for v3 support.

The following files in /usr/lib64/glibc-hwcaps/x86-64-v3/ compare to the

     libbrotlienc.so.1.0.9

This is as of TW 20230331.

Doesn't that indicate that they were not compiled with v3 support ?

It means they have been either built without march=x86-64-v3 by mistake or the resulting binary is the same.

system lacks of post build tests that prove them correctish.
