Comment(by dustymugs):

 The problem I have is that changing this behavior would be slippery slope.
 There are many other functions that assume nband = 1, e.g. ST_SetValue,
 ST_SetBandIsNoData(), ST_SummaryStats(), ST_BandMetaData().

 But the reality is that we need to be able to process many bands at once.

 Just in case, I double-checked how gdaldem handles NODATA for color-relief
 output and it behaves in the same manner as ST_ColorMap.
