Define "now" and "still". Ok, I use my time machine to do that for you
and choose a definition from 1998 for "now" and 2001 for "still". ;)

Seriously, Google filters reciprocal link swaps since ages. Even the
very first issue of the Webmaster guidelines (Dos + don'ts back then
in 2002) told us that they dislike artificial linkage like that
(archived copy: http://sebastians-pamphlets.com/help-google-revealing-the-secret-sauce/
). The filters were improved over time, and with every update more
reciprocal links that exist for the sole purpose of manipulating
search engine rankings hit the dust. Extremely simplified, Google
nullyfies reciprocal links that appear quite at the same time on both
sides, and that goes for triangular link schemes and stuff like that
too. But don't think one is safe with traded/exchanged links when
parts of the link swaps get delayed. For more in-depth information
search the "risky linkage" category of my blog.
