I noticed that many C and C++ libraries in Guix are built with the
--disable-static option. Why are static libraries excluded from Guix?

I'll speak for myself: I remove static .a libraries whenever
they're not obviously required by other software in Guix. If
another package were to require them, I'd first try to fix it to
link dynamically.
Static linking provides no serious advantages and at least one
serious disadvantage: it's invisible to grafting. If A statically
links to B, grafting B will leave A untouched and vulnerable.
My worry is that leaving .a files around will cause some build
systems to silently prefer them to the .so and link statically. I
can't remember the name of the packages, but this does happen.
Static linking is useful in tightly-controlled environments where
space is at a premium, i.e., the Guix System initrd. That's why
Guix has packages like bcachefs-tools-static. It's just made very
explicit.
Kind regards,
T G-R

Could it also do that when the static libraries are split in their
own package/derivation like openssl:static for instance?
