I suspect that "steeper" in this context will turn out to mean no more than the 3.2° approach listed under "Quieter operating procedures" in Heathrow's recent "Long-term hub capacity options" document.
Indeed, also as described on Page 25 of this document,

Not exactly a Space Shuttle Approach (thankfully) but I suppose an extra couple of hundred feet might make some difference to the likes of the chap on another thread who was worried about flights over his pub......
FWIW we're OK for CAT 2/3 autoland at up to 3.25 degrees but I assume since it's only a trial initially rather than cranking the G/S up
we'll be TEAMed and use a "steep" LOC or RNAV approach.
