The hardline answer would be: you want AAA? Avoid having touch targets that are too small.
[Steve] Again my concern is the technique, not the SC itself.  If we want to say AAA conformance means 44 pixel lines, then okay.

If you have content where there are lots of links in inline content which may potentially overlap, this may require you to either create some alternative (like a separate list of all links, as a conformant additional alternative), or to rethink how you present your content, or...
[Steve] You can't have potential overlap if padding and margins are positive, and that's my point.  Putting aside the unresolved issue of focus indicator confusion which creates inaccessibility, do you really expect authors to think about and test their content so much that they will consider all possible viewports, zoom levels, text adaptations, etc. when analyzing for potential overlap?  That doesn't seem feasible to me unless we're also going to produce a tool to do that for them, which I'd argue is practically (and perhaps even theoretically) impossible.
