The usecase of the box heavily influences if a DE is installed. I know a lot of servergrade boxes with a DE, some with just some X11 Apps and no DE, some without any. If you have single machines fulfilling a specific purpose you often have DEs installed and a graphical login. Due to being no part of special focus you often find the default DE of the chosen distro. Noone customizes the DE on those. If you scale some app into a cluster you tend to be without a DE and use some webbased orchestation tools or made-to-fit solutions.
Many GUI Apps are usable without a DE by piping them through a network link. Pure X11 Forwarding is crappy like hell, because outside of any local LAN it takes up too much bandwidth and does have too much latency to be useful, it should really be buried. Even more high bandwidth WAN links don't put those issues really away, it's just crap.
VNC is useable if VNC is not VNC: some advanced implementations using more than the standardized protocol work well enough, but thats putting "VNC" itself as a standard ashame. You need to think which VNC client was the right one to maintain the server you're focussing on.
I often use X2go (which is older nomachine stuff) to launch a xterm, allowing me to fire up some graphical tools from there at good speed. For example baobab is one of my special friends in quickly analyzing what folder on a disk suddenly exploded in size due to some malfunction.
If you need to work locally or use the BMC to offer a remote console or do have a network KVM attached: the current Aspeed BMCs do have enough power to runy any DE if you want to. The current pool of servers I maintain are mostly HPE DL380 and alikes going back to Gen5, thats early intel "Core i" technology, and you can basically bear any DE on all of those.
