--- Comment #4 from Alexey Samsonov <vonosmas at gmail.com> ---
I agree with your argument that suppressions are sometimes useful to quickly
deploy the tool in codebase with large chunks of legacy code. We (sadly) had to
use suppressions ourselves for similar purposes.

However, I don't think it justifies adding a line-number-based suppressions.
This is way too fragile, even for your use case. A simple example - recently
debug info quality in Clang has improved, and it started to produce different
(more precise) line- and column-number information for multi-line statements.
