pre-installed packages bundled into Debian container templates

[WillemBasson]

I just spun up two lxc Debian 10 containers, one using lxc tools on my desktop, using whatever the default lxd template store is, and on on proxmox, using the built in container repository. (Which I since learned gets images from download.proxmox.com) The list of pre-installed packages is quite different - for instance proxmox does not pre-install apt-transport-https, but it does pre-install netcat-traditional.
How are the container images at download.proxmox.com/images generated? Is the rationale for any modifications from the vendor cloud images explained anywhere?

Asking because I don't really want netcat on my containers, but if there is a reason it needs to be there (for the console redirection, maybe?), then I may have to live with it. In which case I just need to know WHY.

while i am not completely sure why exactly those packages are in/not in, you can find the source of the tooling here:

https://git.proxmox.com/?p=dab.git;a=summary (the general tooling for building debian based templates)
https://git.proxmox.com/?p=dab-pve-appliances.git;a=summary (the config used to actually build the templates on download.proxmox.com)

AFAICS it basically tries to do what debootstrap does by default
