Yes, there are good and bad sides to my minimalist solution.  On the good
side, it doesn't make display worse than before (falling back to what lynx
did previously is "playing it safe").  On the bad side, there are tables
where it doesn't do anything useful.

In some situations, the new code can also have the opposite effect.  Table
lines that were centered or right aligned may now be less squished to the
right screen margin.  That probably doesn't happen very often, though.

The TRST code ignores any WIDTH= attributes, so columns should always only
be as wide as needed by the content.  That should also help for keeping
the content close to the left screen edge somewhat more often.

I could get the last table on that page to display in tabular form, with
a line length of 100, after shortening the text in the header cells enough
to fit and removing a <br> tag from one of them.
