And it seems the "problem" is that the satellite is deliberately launched to the standard GTO trajectory, then apparently expected to make the 30+ degree inclination plane change to then target IGSO! I've never heard of something like that for a GSO sat!

Quote from the BDS-3 sat chief designer: "In the past the launch vehicle makes the maneuver to get the IGSO sat from the usual GTO to 55 deg. incl. orbit; now the sat is optimized to maneuver by itself. This increases the sat's capacity and makes the IGSO and GEO sats similar."

I don't understand this (and admit to lacking expertise) - could it be that launching straight into a correctly inclined orbit has problems with the ground track (e.g. worries about where debris could fall)?

No, as 55 degrees inclination orbits are also the norm for the BDS Medium Earth Orbit satellites 10000 km below, of which 16 were launched last year alone.

I can however accept that with geostationary satellites also in the mix, the manufacturer simply takes the GEO satellite design down to the launch trajectory, the only exception being that in this case the satellite moves to increase its inclination. Strange but still make sense.
