Air carrier pilot expressed concern regarding C90's speed assignments for the LOC 28 approach; suggesting utilizing the RNAV procedure as an alternative; adding 180 KTS to FAF in most cases is excessive.

Narrative

LOC Runway 28 at ORD. ATC has been wanting 180 KIAS to the FAF most everywhere we fly domestically. For an ILS approach in IFR situations; that can push the limits of getting configured and in the slot at the appropriate times. For a LOC approach; we need to be configured and on speed by the FAF. We shouldn't be holding 180 KIAS to the FAF on a LOC approach. We need a constant ground speed without a glide slope or VTI. ORD TRACON has been clearing traffic for their LOC 28 and 180 KIAS to the FAF. This is a set up for an accident from all of the configuration changes at a critical time close to the ground. Some alternatives are: 1) plan that any NON-ILS approaches be RNAV approaches so we have the VTI. 2) Plan for final approach speed at FAF. 3) Plan 180 KIAS to a point 3 to 4 miles short of the FAF. And it shouldn't be left to the pilot to request RNAV approach if he wants it; that won't work if there's not an RNAV approach. Even when Runway 28 at ORD reopens to its full length and the ILS is usable again; this should be policy everywhere for an NON ILS and NON RNAV approaches.
