Each library pulls its own set of non-trivial third-party dependencies. For example, libarrow_flight includes gRPC, libcurl and OpenSSL as far as I remember. Worse, libarrow_cuda depends on the NVidia CUDA libraries. That's a *huge* dependency (and may also have runtime costs in addition to installation / deployment annoyances). Some packagers may also want to distribute some sublibraries separately (Linux distros especially tend to like having many small, focussed shared libraries that they can distribute as separate, dependent packages) - but that's not my business and I'll let them speak up ;-) So without deeper analysis I'm a bit worried about this proposal.
