No, replaying the game itself is quite boring for streams, especially when it comes to grinding for morale and resistances. In my opinion, playthroughs of maps without save-loading are the most interesting to watch.
And on this map, there's also not much to do in terms of hero development with the starting army, plus there aren't many interesting ideas or battles with a "wow" effect. It all comes down to accuracy, meticulousness, and patience. It reminds me of a typical old-school offline tournament.
And to understand what actually happened, streams aren't the best option. Even in my own recordings of Metatasker, I often have trouble explaining exactly how things developed due to constant rewinds. Damn, I completely forgot to add the video from the 3rd week of the 2nd month to the Metatasker playlist on YouTube – out of 30 hours of streams, only 10-20% relate to the final version.
For understanding the playthrough, detailed save files are the best way. I usually have them right before and after each battle, plus separate saves for logistical reasons. I can upload them if needed.
And if you have questions about specific battles, I think I can remember the main battle tactics and features.
