Yes, this would work quite nicely!

I prefer #2 -- it looks nice in this-button-keymap.

A way to customize this would be to define a number of keymaps, e.g.

legacy-emacs-follow-link-keymap   [mouse-2] -> [follow-link]
browser-follow-link-keymap        [mouse-1] -> [follow-link]

And then a customizable variable follow-link-keymap which is
a choice between the above keymaps:

(defcustom follow-link-keymap 'browser-follow-link-keymap

The link keymaps will then set the parent keymap to the
symbol value of follow-link-keymap.

This approach does not allow use to use double clicks on a link,
as the first click follows the link -- but that's ok I guess.

One question remains:  How do you set point in a link ?

I'll look into this approach and see what it takes.  For starters,
it should cover:

link widgets
help buttons
apropos links
info links
url links
