I've just come across this issue when I was building a headless
Raspberry Pi with an attached USB speaker. My use case involves
networking the speaker to play sound effects like door chimes and alert
tones. I was installing Raspberry Pi OS Lite (no desktop) operating
system (version 30th Oct 2021), and when installing pulseaudio, apt
reported:

`fontconfig` was definitely a surprise!
After looking at the dependency tree, it seemed that many of these
related to libasound2-plugins. I know that the calculation is not this
simple, but installing libasound2-plugins alone reported:

libasound2-plugin requires 87% or the packages and 96% of the disk
space. I suppose the other concern I have beyond just disk space is
whether any of these "extras" start systemd units, so also burning RAM
and CPU cycles on a low-power platform.
I'd vote in favour of an installation option that does not require
libasound2-plugins.
