You could also use spherical mapping (map_type 1) for your probes - use
something like HDRShop to apply panoramic transformation from Light Probe
(Angular map) to Latitude-Longitude map. Then you can freely switch between
versions. I do agree that it would be nice to support both!

Nice trick, I'll have to try that when I get home! If combined with spherical
mapping (above) then you could have a portable scene file.
