> Does it fix the issue with the multiple buffers and minor annoyances?

The stuff you mentioned so far is all about you not configuring your setup:

- buffers: You configure your clipboard manager to use a single buffer.

- vim: configure to use global clipboard if that's your preference

- X11: dont use legacy software

> No. It just adds a different friction point.

You think using software that implements functionality you deem missing "adds friction", and yet you still want said missing functionality and complain about it is missing.

That's wild.
