What was taken out of the OpenACS 4.x toolkit a long time ago, and
what was taken out of openacs.org last weekend, are two
completely different things.
The huge enormous random list of a bunch of mostly useless objects
related to the user was first added in ACS 4.x, and removed ages ago
from OpenACS, because it was useless junk.
openacs.org, on the other hand, until just a few days ago included a
very useful and simple link from the community-member page to
the Forums page displaying that user's Forums posts. This page was
similar - although much less comprehensive - to the same functionality
found in OpenACS 3.x. Is there really no such functionality
in the OpenACS 5.x toolkit? (If so, that's just plain absurd.)
