We can try this in 2.4 but we should not include any new features in 2.3 IMHO. The release is delayed quite much already and I'm also not aware all the problems it can cause so can't predict the amount of work with it.

I'm no coder, but I've got some experience testing stuff and I agree that it should be left to the 2.4 development version. There's no telling how many things such a change could break and in what ways, so it's better to get a working stable release out now and only then start fiddling with things.
With Shrapnel/Illwinter we had to recall one patch for Dominions 3 in testing phase because it broke the entire game (CTD on startup, no workaround) and there was another patch that had something changed where it caused a CTD whenever you did a specific completely legal action, so it had to be emergency patched right afterward.
For comparison, the suggested change of upping the limits of soldiers is somewhere in between the two Dominions examples in terms of how much it changes, if I'm reading all the references by the coders right.
