Solar float mode: Necessary?
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. ...

IE it is more important to get to full than drop to float at 90% and never reach full that day.
It is all situational. Each "user" needs to keep an eye on what his situation is at the time and place and adapt. Having a Float option on the controller lets you adapt to more situations.
Yes, getting 100% is most important, and yes, it's situational. The more functionality and features controller has - the easier to make it work in one's particular situation.
My controller drops to Float only when the current drops to pre-determined adjustable value. Still not perfect, as there are often some loads running. But better than toys that have only one setpoint (that can be set as either Bulk or Float), so you have to be there and adjust it higher or lower or turn it on and off; or - all fixed setpoints, i.e. you can't adjust anything.
