Feature request Round bed mesh

As the title would suggest Klipper still uses square bed mesh on delta printers. and, its confusing to users. A follow up on this would be greatly appreciated since Delta is becoming quite a bit more popular on klipper with recent new priners. also piezo / membrane type probes seem more accessible.

What are you exactly missing?

Its possible i am mistaken Klipper still uses a rectangular mesh as displayed in the visualizer on delta printers . This appears to be the last discussion regarding the topic in 2018. Question: Mesh Bed Leveling on a delta circular bed · Issue #558 · Klipper3d/klipper · GitHub . Would it be possible to have this feature looked into in the future?
