setup.py only reports successful builds if one or more stdlib modules are missing · Issue #93692 · python/cpython

"Python build finished successfully!" is only printed if there were missing modules:

if self.missing:
print()
print("Python build finished successfully!")
print("The necessary bits to build these optional modules were not "
"found:")
print_three_column(self.missing)
print("To find the necessary bits, look in setup.py in"
" detect_modules() for the module's name.")
print()

Either we print it every time the build succeeds:

diff --git a/setup.py b/setup.py
index 4c497346e8..e87da57a47 100644
--- a/setup.py

Or we just remove that line from setup.py.

I'm fine with either.
