As a practical matter, is float mode necessary with solar charging? As an alternative, the controller would simply stop charging when the battery was full. The next day the process would repeat. ...

If using a controller w/o float, if you drew AH from the fully charged battery and there was still sunlight, I would expect the charge to (resume in order to) keep up. Albeit at 14.4v, not 13.2.
The controller is kicked back into "Boost" when the battery voltage gets down to 13.2. You could run some loads late afternoon and only get down to 13.3v. Of course there is loaded voltage being lower, so it also would depend on how big the load is.
