How to use EPSG 3857 for tiled image layer?
Try the BasicMercatorTiledImageLayer It should work with the EPSG:3857. The OSMMapnikLayer extends it for properly displaying OSMs mercator projection. It has been sorted out support for full WMS-layers by combining the map boundingbox with top level events.
How big is EPSG compared to WGS 84?
Relative to WGS 84 / World Mercator (CRS code 3395) errors of 0.7 percent in scale and differences in northing of up to 43km in the map (equivalent to 21km on the ground) may arise. Certain Web mapping and visualisation applications.

Why is X not a point in EPSG?
The reason is because is not POINT (36.5277099609375 -5.86424016952515), but POINT (-5.86424016952515 36.5277099609375) because longitude and latitude depends on the system. Normally X=longitude and Y=latitude, but e.g. in Google Maps X is the lat and Y is the long.
Why is projnet cannot read this epsg.io version?
I understand you’ve made a distinction that WKT is not intended for 3857 because it assume a spherical earth. And yet epsg.io/3857.wkt does exist as does ProjectedCoordinateSystem.WebMercator.WKT. Why is it that ProjNet cannot read this epsg.io version?
