There's literally no good reason to have maps back other than 'muh nostalgia'
there are many reasons for it?? modter collision is far from perfect, is far laggier when trying to create things on the scale of the bedroom or larger, and is not as compatible with water bricks and the like? they also take far longer to create when it comes to large scale creations.
for example, if you were to make a dayz map, it would be far easier to use interiors or even terrain to create the island, then add builds and such as necessary, without compromising how drivable/compatible with vehicles the map is, having underground/deep areas in the island while having an ocean of water outside and around the main island, and controlling the scale and layout of the build without spending lots of time ingame running around/rebuilding pieces/moving camera to get a sense of the scale and spot problems.
also, if you didnt notice, the draw distance limit has been
severely cut down from pre-v21 levels, which contribute to the anti-big-scale environment status of the current version. in the past you could see the entire ice palace build and road within an 1250x780 frame,
zoomed in to the lowest fov. if maps are going to be gone forever, this cap should at least be raised so its more possible for creators to create large scale works, even if it takes them far longer.
compared to this, your only reason to not bring maps back is that it looks dated. In the hands of the right creators, it is possible to make it not look as dated, or allow them to focus time on other aspects of their server to make it feel more polished and thus draw attention away from the dated aspect.
