I used to do this 1/2" cut as well, but this will last for only so long. I am not sure what the OEM rubber is made of, but once it start changing form (expanding), the end of the hose is near.
The first sign is that slow seep at the clamp level - fixed in Ricky Bobby's DIY by cutting the 1/2". The 2nd sign is when these hoses start to sweat the ATF through. In my case, the "fix" lasted less than 1 year, after which I changed the hoses altogether.

Another aspect of the equation is the fact that there might be a flow restrictor in the feed line (I am not 100% sure about this, but I did some reading, and one can experiment trying to flush the ATF - take the reservoir off, you will have 2 open ended hoses, one should go in an empty jug, the other in a fresh jug with ATF - if you are not careful, i.e turning the steering wheel too fast, you will empty the feeding jug in seconds and suck in air - the jug to be filled will fill also in seconds and will overflow - hence the need for a "controlled" flow in the steering lines). That restrictor has also the role to guide the PS hose(s).

just my 0.2
