TCUNZL64.DLL \ TCUNZLIB.DLL: doesn't need anymore If using xp+ ?

The behaviour described in the bug report is either by design, or would be far too complex/time-consuming to be changed

No, TCUNZL64.DLL \ TCUNZLIB.DLL is used for regular deflate, while tczstd64.dll / tczstd32.dll is used for zstd files (which is different from standard zip):

It is used mainly for tar.zst files.

The dll is still used for these cases:
1. Extracting thumbnails from the thumbnails cache. TC will recreate all thumbnails if the dll is missing.
2. Unpacking ZIP archives with BZIP2 and PPMD compression. You will get an error when trying to unpack such an archive.
