Code review comment for lp:~andreas-pokorny/mir/libinput-platform-pointer-settings

... or I might use unique_ptr instead, and then do not have to bump the input platform abi when adding properties to the structure. And there we are again: Now I have to make sure that the library outlives the lifetime of the structure since it is the only one that knows how to delete the added values.

So in the end using UniqueModulePtr was a partial solution to ABI changes (it only ensures old mirserver works with new input library not the other way around)...
