If you want to break the ABI you must bump the SONAME version. Not
that bad of idea, but should you _explicitly_ ensure that say no API
gets removed.

Before you ask - there's [at least] two components which link against
libdrm_amdgpu.so and have unresolved/unsolved symbols. If any symbol
gets removed existing, these packages will break.

This is how things broke with nouveau and you don't want to repeat that.

Tl;Dr; I'd opt for Christian's suggestion ;-)
