Possibly ambisonics is different - but not all multichannel audio uses ambisonics - certainly with vbap for example if your speakers are wide apart you don't want a big gap when panning between them then wider dispersal would be advantageous if the speakers are very close together I could see it would introduce coloration when the directivity of the speakers overlapped - with wavefield synthesis the smaller the gaps between speaker cones the higher frequencies can be succesfully spatialised - so I guess for wfs more "pinpoint" directivty would be preferred - I may also be wrong ! For creating true walk around 3d soundscapes with no sweet spot for me a useful tool would be a driver which would be a sphere which put out sounds in all directions (360) - because thats how sound often propogates in real space (eg a twig cracking up a tree will not just put out sound in the 180/90 degree space on one side) The dispersal pattern of speakers isnt often considered when building these kind of systems so its an interesting topic !
