Okay, have done some testing with the 0.4.1c and here are the results:
I think the population ration is more or less good for now, as it is now more or less guaranteed that there is at least one adult noble arriving during the first two immigrant waves. Or at lest that's what my 10+ test embarks gave me. Current real ration, as in how the popration shows in fortress, is also rather good. For example, one of the fortresses I used in testing had 97 dwarves, of which 58 were commoners. Of the remaining 39 dwarves 14 were holy dwarves, 15 were warriors and 10 were nobles.
The lesser golems work just as supposed. Those are pretty costy to embark with but one such creature, especially if it's trained to war, can hold out narrow entrance pretty well. The problem is that the lesser golems hardly ever comes unclaimed as pet with immigrants, which means that you have to either buy one stray golem from caravan or embark with one. And so far haven't seen any golems brought by caravans, though that doesn't mean anything yet. But yeah, to fully weaponize golems you must embark with one, then train it to war. The training is required due the high cost (iron war golem was somewhere over 8000 bucks IIRC).
I have also done some tweaks and fixes. First of all I fixed the problem with dismantling furniture. The problem was that there was this [REACTION_CLASS:] tag in the reactions but no such tag existed in materials. It should be fixed now, though haven't actually tested it out yet.
Another fix was with kobolds. I realized few days ago that I haven't seen a single kobold in any fortress as far as I remember since DF 31.25. When I checked the raws I noticed that the kobolds have BONECARN but no NO_EAT or NO_DRINK tags, which are mandatory for any carnivore entity due the flaw in vanilla DF. So I decided to give the kobolds those tags, which means another hostile entity...
Lastly I tweaked the reactions that produce Sacred stones from rocks. Basically I gave the [REACTION_CLASS:HOLY_STONE] to the reagents in both reactions and the slapped that same tag to all stones that aren't either metal ores or flux stones. In 0.4.1x versions the game could use any stone, which means even ores were used. Not anymore.
Things to come:Currently I'm working with more reactions to Weapon Workshop. This includes possibility to make several specific weapons from specific special materials, for example hammers from gold or silver or spears from obsidian. I was also thinking of removing the old obsidian sword thing introduced by vanilla game and replacing it with custom reactions to make it work as it should. Axes could also be made from obsidian.
EDIT:
HOLY CARP! I just had a moment when two lesser iron golems and one lesser steel golem slaughtered the whole goblin invasion! Around thirty goblins, three of them being elite, archer, hammerer and lasher. And none of the golems died, though all of them are gravely injured.
