Usually this is the better option for C++ libraries,

Symbols files have two purposes:
1. detect ABI breakages
2. don't create unnecessarily strict dependencies on the
latest version of a library
You are talking about 1., and I agree that any proper ABI checking tools
would be more useful than people just blindly updating symbols files
from the buildds without properly reviewing every single symbol change.
There is also the point 2. which was AFAIR the main original motivation
for symbols files, but IMHO the C++ symbols files mess is not worth it.
The wiki contains some information from Simon McVittie regarding
upstream of a C++ library solving this with proper symbol visibility,
but this is something for upstream to implement.
