compatibility - Consider shipping an empty wiring_private.h

[KurtE]

There are several libraries out there, like most of the Adafruit display libraries for whatever reason include this file.
Obviously, the library owners can add some additional #if type statements to avoid this in this case, but you probably will get forum threads for a lot of these libraries, like Adafruit_ILI9341, that can easily be solved by simply putting in a blank file. Or maybe one with a #warning

Just a thought.

There may be other such files that should be considered as well.

In an ideal world (I'm well aware that we live in the real world, but let's keep some goal in mind), internal "private" files should not be used by 3rd party vendors. Please consider opening an issue report or PR at the affected repositories. We can not provide workarounds for what constitute API violations in the first place.

Understood. Personally, I prefer to be pragmatic on issues like this.

If I were someone releasing a new board, one of my top goals would be, to have as many things as possible work without having to rely on 3rd parties to have to change things.

As for opening up PR/Issue against all of the different libraries. I do on case-by-case basis. As for proactively doing so, I would have thought that Arduino would have done that as part of the beta process.

For now, when it come up again on the forum, I can at least point them to this issue.
