Personally, I would prefer that technically oriented first stages do not come with hoses.
I had a discussion with the Atomic representatives about that once. In the case of the Atomic M1 which is used frequently for decompression tanks, the 30/32 inch hose is inadequate. Almost everyone that I know has to replace it with a 40 inch hose.
If you have one first stage like the xdeep turret that might be used for single backmount diving, twinset backmount diving, sidemount, or deco / stage / travel gas the hoses will all be different lengths. Rather than have a pile of useless hoses, you can get which hose fits properly depending on the application.
