I'll be honest - because of the wild variance in whether .h files are
listed in the [sources] section of .inf files, I have always been
unsure as to whether they were just being ignored (and extracted on
the side via mkdep or similar).

If the intent is to speed up build time, would it not be better to
warn the user - so they notice the problem and fix their modules,
rather than adding extra processing time on having the tools work with
broken .inf files?

This does not look like material for edk2-stable201905 to me.

25% is a big number, so I won't argue against this. But I also won't
argue for it - the BZ was raised very late in the cycle.

I can see how the current behaviour could cause problems with some
CI/build systems. If it is properly reviewed and tested, I am OK with
this one going in for edk2-stable201903.

This looks like a new feature - not something that should bypass the
freeze period for edk2-stable201905.
Can you explain why this is needed in the stable tag as opposed to
being available from master the day after the tag is made?

Best Regards,

Leif
