Those minutes are mostly about Canvas a11y; the changes in discussion off no a11y solutions not progress.

A reusable Canvas Path object means a (very slight) speed up in redrawing as the implementation can keep some basic calculations around. Very slight.

The change put forward by the editor doesn't address accessibility nor is it designed to optimize the efficiency of Canvas rendering.

It is a broad change, instead, to the Canvas 2D context in an attempt to implement Doug's "COG" proposal.

I don't understand why Ted or Anne think this change set is something else.

The change is very broad. If the editor were addressing the TPAC conversation, it would have been done with a minimum of changes.

Such as:
ctx.addEventTarget(element); // bind current path to subelement forwarding pointer events for hit testing.
path = ctx.createPath(); // create an opaque path object for re-use in drawing commands.
