this is a good idea

I don’t think it addresses any of the issues raised —but it is good advice where it can be applied

Essentially, I wanted to say that for a given visual presentation of content, make all targets as big as they could be without necessarily having to change anything visually.  The entire table cell, tab, accordion header, control+label, etc. should be included in a target.

The exception for "more than one target" is meant to handle situations such as tables where multiple controls may reference a single label using  aria-labeledby  or similar technique.

Perhaps I’m naïve, but it seems to me that the very small in-line targets that people are trying to exclude would be the worst cases for the users with dexterity issues. I think this entire problem calls for a “user agent” solution.

There have been allegations about other formatting problems that would make the resultant material hard to read. So perhaps a narrow exception to cover just those cases would be in order, rather than a broad exception for “in-line” controls and links.
