Basically, it's like distributing a single static binary in a tar file, versus distributing a dynamic binary and all its dependencies in a tar file. The whole purpose of using a tar file is to keep multiple files.

You can make a smaller tar file by including just the static file (less inodes/wasted file space of deps linking to each other/unnecessary extra function call data). And technically static files can sometimes execute faster (depending on page/cpu cache etc). But the advantages of static are much smaller when you consider the advantages to dynamic in a tar file - and even more advantages in a container.

So while there can be advantageous, they are vanishingly small.
