When I was an examiner, I would have expected you to fly the approach
profile as published. Once upon a time I decided to forego the "descent and
maintain 2200 feet" on the way in to BFI's ILS 13R, thinking that I would
stay at 3000 and intercept the glideslope high....got chided by Seattle
Approach for doing so. Over the years I have learned that ATC expects you to
do the expected.

The industry has worked hard to get away from dive-and-drive. A constant
descent profile is a lot safer, provided it doesn't bust a stepdown. If a
stepdown is mandatory it will so state on the Jepp chart, and have a line above,
as well below, the altitude on the NACO chart.
