It depends...
Let's say you have 10 coinjoined utxos worth each 0.1 bitcoin.
When you consolidate all 10 inputs in a single user transaction, then everyone knows that these 10 inputs belong to the same person, this is new knowledge that wasn't public before the transaction.
However, it's not so obvious which other coinjoin outputs you have, and which pre-coinjoin inputs you have.
There are like 3000 "fresh" bitcoin joining the wabisabi pool each month, so there are hundreds of new "1 bitcoin users" in this month along. Since 2018 Wasabi had over 300000 fresh bitcoin, and even the first user could have coinjoined for all these five years, only to now make a 1 bitcoin consolidation transaction.
It is however not great to reveal your entire wallet balance by a full wallet consolidation, better to make two or three separate transactions that spend a small portion of the wallet balance.
Finally, with WabiSabi this isn't a problem at all anymore, because you can anonymously register multiple inputs in the same coinjoin transaction, and thus consolidate privately without revealing common input ownership heuristic. Payments in coinjoin is a further improvement.
