I don’t think that high-res icons, vector fonts, aliasing and composition meaningfully effect today’s hardware — we can and do have GPUs barely sweating on even much more demanding functionality and these are mostly parallelisable/easily cacheable things. If anything, they take up some GPU memory.

What makes some of today’s apps resource hogs is the different abstraction level which can be useful (accessibility was absolutely not something important back then and even today it is not without lack), cross-platform, but often much more leaky than it could be.
