This is constant with keyboard events bubbling up from the subtree. It's also controversial, as the elements in the subtree would retain path information to be used by the UA in delegation of onmouse and onclick events. Vendors would likely re-use hit testing from svg code paths.

Hm, okay.  How much of this is simple desire for hit-testing, and how
much is actual desire to retarget clicks to the subtree?  Just wanting
to uncover the underlying problem that devs are trying to solve, so we
can solve it well while still smuggling in accessibility.
