The idea of scaleable pixels is somewhat different: user can select
big/small fonts in the OS/application settings and font sizes would be
multiplied by some factor, for example 1.5.

BTW, why use font size in points? As other elements, like widgets,
images, etc has size in pixels, it's better to use pixels for fonts
too. Auto HiDPI scaling in Qt works for font sizes in pixels.
