Because those steps are just a linear interpolation of the values at
0.00 and 1.00? ;)
If you really want steps, you'll need to specify two colour values for
one and the same parameter values, e.g.:
density_map {
[ 0.00 rgb <0.39607808, 0.45490193, 0.97254896> ]
[ 0.25 rgb <0.39607808, 0.45490193, 0.97254896> ]
[ 0.25 rgb <0.54705858, 0.59117645, 0.97941172> ]
[ 0.50 rgb <0.54705858, 0.59117645, 0.97941172> ]
[ 0.50 rgb <0.69803905, 0.72745097, 0.98627448> ]
[ 0.75 rgb <0.69803905, 0.72745097, 0.98627448> ]
[ 0.75 rgb <0.84901953, 0.86372548, 0.99313724> ]
[ 1.00 rgb <0.84901953, 0.86372548, 0.99313724> ]
[ 1.00 rgb <1.00000000, 1.00000000, 1.00000000> ]
}

Look up "function pattern" (not to be confused with "pattern function").
