I think sort of the opposite happened, Qt5Core got to its size because
there are useful features that non-GUI applications might want that
were moved there. Like QRegularExpression, you could easily see that
being useful in all sorts of server/daemon applications. Stuff that
only GUI needs stayed in QtGui and friends.

This whole discussion reminds me of this recent article about Linux
slimming down the ipv4 stack:

Like Qt there's no low-hanging fruit, just a bunch of things that can
be stripped out that together would add up to a meaningful decrease.

Unlike the Linux networking maintainers, Thiago is open to
configure-time methods to slim down QtCore. That seems like the way
forward for people who care about such things.
