Not yet, it was a deliberate decision to not make it the default
enabled, cf. 

  * mm: Enable Multi-Gen LRU implementation (not enabled by default)

in 6.1~rc5-1~exp1 which was after getting feedback from Ben in
https://salsa.debian.org/kernel-team/linux/-/merge_requests/568 .
It is likely to early to have it in bookworm, and user wanting to
experiment with it have an opt-in solution.

We might re-evaluate this post-bookworm release.

Salvatore
