My thoughts are similar (extends your idea). Add two configurable 
boolean options (don't know if the names are good):
$USE_TITLES_AS_ANCHORS
$USE_TITLE_LABELS_AS_ANCHORS

a. $USE_TITLES_AS_ANCHORS=0
    $USE_TITLE_LABELS_AS_ANCHORS=0
    -> works exactly like it does now; default setting
b. $USE_TITLES_AS_ANCHORS=1
    $USE_TITLE_LABELS_AS_ANCHORS=0
    -> uses the section title as anchor; if it's not unique an
       incrementing number is added
c. $USE_TITLES_AS_ANCHORS=0
    $USE_TITLE_LABELS_AS_ANCHORS=1
    -> uses a symbolic label as anchor; if it's not present the label is
       based on the section number
d. $USE_TITLES_AS_ANCHORS=1
    $USE_TITLE_LABELS_AS_ANCHORS=1
    -> uses a symbolic label as anchor; if it's not present the section
       title is used; if it's not unique an incrementing number is added

This is good for backwards compatibility and let's the user some 
freedom. Some users will want to use symbolic labels throughout the 
whole document, others (like me) want to use the section titles and 
again others may rely on the current behaviour.

Another idea:

I assume if users want to allow links, which are "safe for updates", 
they probably want the names of the html pages as strings (can be 
achieved using $LONG_TITLES) and the anchors we are talking about as 
strings. That's why it is probably good, if there were a single option 
for this.

I know it's not easy to implement this, but it would be a really great 
enhancement for latex2html (at least people immediately requested this 
"feature" for the document I maintain). Thanks for your interest and 
best wishes for the new year.

Jens
