Can I reduce the number of embedded fonts?

Question

My 63-page document uses four different fonts, Libertinus Sans, Libertinus Serif, Libertinus Math, and Latin Modern Mono. It contains several diagrams with text in Libertinus Sans that were exported as pdf from EazyDraw on macOS and included in the document with \includegraphics. The document was compiled with lualatex.

The output from pdffonts is surprisingly long:

Questions:

Why does the same font/type/encoding combination (e.g. LibertinusSerif/CID Type 0C/Identity-H) appear twice? Different font sizes perhaps?
The different combinations of LibertinusSans with type/encoding seem to be related to the diagrams being included. Is there are a way to "reencode" things to make fonts more consistent?

This is a consequence of subsetting, and is not unique to TeX. The funny-looking code before the font name is an internal label, which describes the subset. Also, if LuaLaTeX (via fontspec) loads a font with different properties, it may be treated as different subsets. For example, according to the fontspec manual, loading a font with different inter-word spacing will do that. — , Jan 03 '18 at 20:49
