[texhax] SO: What to do with this hyperref note on amsmath?

Hello,
I put a question¹ on stackoverflow but I seems to get no answers.
It is about a note (copied below) in hyperref README:
,[ /amsmath/ ]
 The environments equation and eqnarray are not supported too well. For
 example, there might be spacing problems (eqnarray isn't recommended
 anyway, see CTAN:info/l2tabu/, the situation for equation is unclear,
 because nobody is interested in investigating). Consider using the
 environments that package amsmath provide, e.g. gather for equation. The
 environment equation can even redefined to use gather:

 \usepackage{amsmath}
 \let\equation\gather
 \let\endequation\endgather
`
But the space between 'hello' and 'equation' is different in this example:
\documentclass[twocolumn]{article}
\begin{document}
hello
\begin{equation}
a+b=c
\end{equation}
hello
\begin{gather}
a+b&=c
\end{gather}
\end{document}
So technically gather cannot replace equation. Thus, in a document using
both hyperref and amsmath, what is the best replacement for equation?
Thanks.
Leo
