If MM wants to make more things like the Lolth Patron warlock (which seems to be the source for the MToF's arachnomancer's abilities) and maybe some 4e-style summoning (not to mention converting some 4e monsters to 5e), that would be great. If that stuff makes into print (or the DMs Guild), that is better yet.
Even if it does go into print/DMs Guild, there is no guarantee that the fluff would be exactly the same as in the video series. There is a big difference between playing around with something and making something for production.
