Instead, why not just revert the breakage and have IBM look at another
way to implement this that does not break the ABI?  I understand that
this essentially is breaking ABI again, but it might be better than
bumping soname since that makes it three ABIs instead of two.

That is, with a soname bump you have:

- The original ABI
- The broken 2.19 ABI
- The soname bumped ABI

with a revert you have:

- The original ABI before the patch and after reverting
- The broken 2.19 ABI
