I find all three of them very useful! For example, this intconn thing.
So far the only solution I could find was to add a layer just for this
internal connection.

I searched versions back to 2006 to find a version where globals.h fits,
but couldn't find one. As I don't really understand what the code in the
patch does, it'd be a bit of gambling to force it in regardless.

How about putting your whole work into the central repo?

Questions to the audience:

- Do the above three approaches look good? Better ideas on how to
implement the functionality (i.e. without a pin flag)?

- With all three examples implemented, is it still a good idea to allow
arbitrary flags?
