Has the time come to get rid of the "delivering" of public headers?

that's one way of doing it, which would require all headers to be under
a new top-level directory.

not sure whether we have other options as well, e.g. how would this work:

- module/inc contains the public headers of the module
- module/source/inc contains internal headers of the module
- put top-level dir in include path

advantage is that headers stay in modules, but would require changing
all "#include <module/foo>" to <module/inc/foo> ...

would need to try that out on Windows, but my guess is that even if it
doesn't blow out command line length limits (which could be worked
around with a response file) it'll make the Windows build a lot slower
because compiler has to try out all include paths (well statistically
half of them but that is bad enough) for every included files, and those
file accesses take forever on Windows.

agreed, gives us some time for bikeshedding :)
