Approach idle mitigates a good deal of that snag. MABH on my jet is 17" as I recall.
In my airline we class anything over 3.2 degree's as a steep approach and it must be flown fully stabilised from the FAF. The real issue would be slowing the jet if you didn't especially in turbulence or with a tailwind. Can't really see decelerated approach's happening at 4 degree's somehow
