Two dozen other packages are linking directly with libLLVM.so.

Are you happy about libclang.so being a shared library?
libclang.so uses libLLVM.so, which adds another 10 indirect users.

Debian ships 30k source packages that build 60k binary packages,
with 3 years of security support (plus 2 years LTS).

It makes things a lot easier from a distribution point of view if a bug 
in libLLVM can be fixed just there, instead of having to additionally 
find and rebuild the 30 or more source packages building binary packages 
that use libLLVM in a security update for a stable release of a distribution.
