Thanks.  As a prerequisite I'm going to install this patch:

Keeping traditional behaviour means not jumping to the middle of the
*Occur* output by default.  Then maybe we could use the same option
to highlight the current line and to jump to it?  Like the existing
‘list-matching-lines-buffer-name-face’, adding a nil/face choice for
‘list-matching-lines-current-line-face’, so when it's nil then don't
highlight/jump?
