GeoServer has had forceXY enabled for as long as I can remember (at least since 2007 <https://github.com/geoserver/geoserver-history/blob/9089b856fa47ba3110368f945b0835bf69753da2/geoserver/main/src/main/java/org/vfny/geoserver/global/Config.java#L44>), I don't see it being changed any time soon, mostly because of practical reasons, it would take a significant effort to un-set it and keep everything working (but, if anyone is reason that wants to work on it, that would be welcomed!). There are also a few Geotools modules that are not working properly unless the flag is set, JDBC sources come to mind, where typically the SRID is just a number and needs to be interpreted in east/north order. If you want to make sure a "EPSG:XYZW" code is decoded with the native EPSG axis order, a quick trick is to switch to the URN notation instead.
