you could reinstate the removed symbol to restore compatibility […] this would be the least disruptive solution

If you do this, you would also want to increase the compatibility minor version (the number you pass in the -compatibility_version flag) to 1.2.0 (from its current value of 1.0.0). After all, any program linked with library major version 1 minor version 1.2.0 or later will not run with library major version 1 minor versions earlier than 1.2.0 since they do not have the new __ZN6snappy11RawCompressEPKcmPcPmNS_18CompressionOptionsE symbol.

We discussed a bit. We will restore the symbols in 1.2.1. Usually all Google libraries support strong API compatibility with no promise of ABI https://abseil.io/about/compatibility. We understand from the long history of snappy that it created a case where enforcing will create more problems
