For the record, the reason why is well-documented in "man nsswitch.conf".

And, in fact, you might be able to eliminate your need for many run-time
dynamically-linked /lib/libnss_*.so.2 files by tightening up
/etc/nsswitch.conf to look like this:

passwd: files
group: files
shadow: files
hosts: files
networks: files
ethers: files
protocols: files
rpc: files
services: files

That changes the default by not referencing
/lib/libnss_{compat,nis,dns}.so.2 so you only need
/lib/libnss_files.so.2 for all services.
