Upgraded wells

With the latest snapshots new "water under" condition, I wonder if wells could be tweaked (incl desert ones), so that instead of a fixed depth well full of water... It could have a chain above a water filled cauldron in the surface part of the well and a pit straight down to an underground water source, be that an aquifer or flowing water. This would improve the use of wells, also if vertical chains could act similar to dripstone for filling cauldrons with water, provided they are touching a flooded block from below (unlike dripstone that needs a block between) then a flooded half slab above the chain under the well roof would refill the well's cauldron over time, if emptied.
