There was a time when I liked that sound too, but it hasn't aged very well in my ears. Without the mids it sounds insubstantial and "unwarm" to me today. It takes the note out of the tone.
That said, it has its fans even today. Just read an interview with Meshell Ndgeocello where she said that she is switching bass brands yet again in search of a bass sound as zingy as on those Level 42 albums of yore. She also sings praises on Mark King as a bassist in that interview.
The bass on Starship's "We built this city" is another example for how a 20/20 sounds.
