To be honest, I don't remember any discussions about maps for HotA in this thread. But that doesn't mean people aren't playing them. Keep an eye on the feedback. And even better, perhaps leave similar feedback on the sites where you downloaded these maps. There, this feedback will be very useful, as people often hesitate whether to download a map or not, and their opinion is often based solely on the minimap image and the comments under the map.

P.S. If I understand correctly, the main problem with maps for HotA is that its team makes constant updates; a super-map made a year ago can be broken by some updates in the mechanics. That's why everything is stable and unchanged with SoD. But this is the opinion of someone who doesn't play HotA

I wouldn't say that the updates are constant. There haven't been any major changes for a long time. The last significant one was when Conflux was deprived of the grass bonus, and a different landscape – highlands – was introduced. And the nerf of some secondary skills, like logistics and intelligence, also made adjustments. Indeed, this could have broken some maps, but not critically for everything. Soon (about 2 years ago), they should add a new Castle and new units and heroes, which could also break something. But overall, this shouldn't interfere with any games here and now. And plus, if a map is relevant, the author can also update it.

I think the main problems are the conservatism of the community (to a greater extent) and the inability to connect SoD save files (to a lesser extent). Well, maps for HotA are being created; we just need someone to create a popular masterpiece, which currently only exists in SoD.
