Welll...the 'real' answer why people seldom do it might be "that is too much sailing and too long between bars...I am on vacation"
For others, that is open water and potentially out of sight of land....
and finally St Croix has a bad reputation in some quarters...
I'd personally give it a shot some day, but the Spanish islands are first on my list. Then a reach to St Croix and a reach to St Thomas would be cool.
