Adding such would simply add another unit to an already crowded OOB. But they would cost about the same as a 105mm battery, so 99% of players would pay the few points more for the greater shell size.

The British in Burma tended to use the 3.7 inch batteries as long range arty as well, due to lack of trade in the AA role. But adding a "3.7 used as arty" battery would also clutter a crowded OOB, and be of the same effect as the existing 25 pounder battery really.

What can't be modelled in the game (for off map units) is the extremely flat trajectory of such high velocity AAA guns. They basically could only fire at hill-tops and other such LOS targets visible from the rear areas. So best ignored, or simply buy some on-map 88s and snipe from the rear areas at what you can see with direct HE especially if playing a larger map. (And if you are going to spend those points - then why not just buy a 105mm, again? - at least it can fire indirect, as well as having a bigger bang).
