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. ...

Does "all conditions" include when you will be doing an "incomplete recharge" by dropping to float, when you could have reached "full" before dark if you had stayed at Vabs?
??? Float is best when fully charged. Float is also good when battery has somehow not fully charged.
The alternative (see OP) is not more Absorption but rather to just turn the solar power off. Yes IMO float is better than off in ALL conditions.
Yes it is best to get the battery 100% before float and that does require a very good controller to adjust depending on conditions.
