Yes, it is possible to make the links always visible by changing the CSS.

For @def* and @*table there is a clear "heading" which the link can
be attached to.  In contrast, @anchors (like index entries) could be
anywhere.  I don't think it would always look good to have a copiable
anchor link (what do you call these things? - "permalink" seems to be
promising too much) and there may not be a good place to put them.
As with index entries, I feel that @anchors should be invisible at
the target (although it would be interesting to see any examples from
documents where having a copiable link for an @anchor would work well).

Texinfo's own manual mainly uses @anchor for renamed nodes so that
old links still work.  Copiable links here would not be useful.
