I used the position but somewhat further in the variation to do some testing of two different versions of Glaurung Mjolnir. More to get a feel for the differences than exact testing.
The second version of Glaurung Mjolnir only differs in the place where the King safety is calculated, it was moved to after the calculation of Pawn storms (those are calculated mainly if there is opposite castling I believe) and more importantly even after calculating passed pawns. The place has become potentially important because now King Safety has become a modifying factor of that part of the the total midgame evaluation that is calculated before it, just as the eval has become part of King Safety.
There is something to be said to just move King Safety totally to the end of the evaluation routine then but it is worth some experimenting. For instance now I think that passed pawn eval in the new place should/could go up just a little because a certain portion of it will now be subtracted in King Safety. But mainly the objective was to see if I could detect some differences overall.
This is a position far in the endgame so King Safety should play only a neglible role, but still it is good to check this. Positional effects are probably just about the most important effect that one should investigate for any new introduced term. In my opinion anyway,
I think I prefer the second version because it gets a nice score in later iterations, but the choice is not so easy and any differences could mainly be noise so far in the endgame. The position was taken 11 moves after the first position so it should be easier to see a win:

Build 1 with the same UCI optional parameters, but earlier calculation of King Safety, build 1 was faster reaching depths around 34 but did not reach such a high score, and in the eval it stayed with 13.Nc5 Bc8 14.Ke3 where I think Build 2 may have found some better moves, judging by the eval, also in another version that plays 14.Nf4, here even 13.Nf4. I let Build 1 calculate for more than 300 minutes. On the other hand: it is also nice to see the consistency in the analysis from depth 32 through 39, I could well be wrong but this may be really different from older versions of Glaurung I at least would not have expected it, also because I increased selectivity and other extensions even further and those other crazy changes
