I stand corrected... sort of.

[+] It's reasonable for an author to expect a heading like "!!See
also" never to change.
[+] It's extremely easy for an author to learn target a section by
name (#see_also for !!See also) without peeking at the HTML source.
[+] An author who knows about the feature can be expected to
understand that fragment ID will change when the heading changes.
[+] It's easy for an author to insert a [[#see_also]] anchor when
changing the text of a heading.
[-] It's *not* reasonable to expect a "!!See also" link to remain the
same in a dynamic-number system.
[-] Guessing a headings dynamic-number name seems error-prone at best.
[-] Inserting a heading manually in a dynamic-number system will not work.

The point is that neither is perfect, IMHO one is unworkable and the
other is pretty good.
Sounds like I'd use it and you wouldn't. There are a lot of features
like that in PmWiki, which is why
$EnableAutoAnchors = 0;
or something similar will be available if the feature is added to the core.
 (:pagelist:) could be used to discover if a link with the anchor exists.
