Hard build errors are treated as mere warnings

Whenever I make a mistake in my Qbs files some warnings will pop up in the issues view in QtCreator on the following form:

some_qbs_file.qbs:19: warning: Property 'configure' is not declared.
some_qbs_file.qbs:15: warning: Error while handling product 'libcombined':
:-1: warning: toPrimitive
some_qbs_file.qbs:15: warning: Product 'libcombined' had errors and was disabled.

If I have warnings enabled in QtCreator it will look like this;

However if you disable warnings, which is a very common practice for large projects, (or else you will be distracted by a jungle of warnings all the time), it will look like this:

Please notice the distinct lack of any indication that half my project won't be built today.

I would like to see the following changes:

• When Qbs drops a whole file because of errors, it should be notified to the user as an error.
• This "show as an error or warning" thing should be set as an option in project Qbs build options, with the default being "show as error".'
• When entire parts of the project are disabled due to errors, it should be mentioned in "General Messages" as well, regardless of what options are enabled/disabled.
