Only in abandonware software private APIs stay the same. In current, living technologies, they always change. Apple can simply issue an update to all consumers of the API so that they start using different symbols. If you have the energy to play this game, then it's fine. Just remember that Apple doesn't have any problem with killing the whole kernel extension market (this among lots of other things).

At my work I'm also forced to use private APIs on macOS and it's always a mess. Each update is a source of stress. Sometimes there's no work to be done, sometimes I need to spend a month to figure out what's happening.

I generally discourage people from using private API and I always say that if the platform doesn't allow doing some kind of software using public API, then don't do this software for this platform. Select a different platform. Use feedback forms to request functionalities. But using private APIs is asking for trouble. Again, if you want to play the game then it's fine. But if you offer software for users, then you're in some way responsible for those users as well.
