I expect such cases to be rare and dealt with on an as-needed basis.
Generally, projects either bundle or don't. The fuzzy area might be
with plugins, I guess.
Not just plugins, anything that happens to compile the bundled library
into a DSO (either by itself, or as part of a larger sub-component) will
likely leak colliding symbols, unless special care is taken not to.
If we expect more bundling, then we need an alternative to the current
ELF linking model, IMHO.
