Absolutely well earned.

I'll make sure to review those bugs, thanks.

We should modify the introspection scanner to allow taking a list of files.

If the Python setup/teardown cost weren't so high, I'd even look into
running g-ir-scanner on individual files, generate intermediate
introspection data, and then have a "link" phase to generate the XML;
that would also immensely help with incremental builds.

Supporting Visual Studio pre-2015 is going to be hard; various modules
are trying to standardise on a C99 pipeline, and I'd rather move away
from nearly ten year old development environments if that involves
work on our side.
