Mainly because there was no warning at all in v12.2.1 and it just
appeared after upgrading to v12.2.2. Besides,its not a "too high" number
of PGs for this environment and no CPU/peering issues have been detected
yet.

I'll plan a way to create new OSD's/new CephFS and move files to it, but
in the mean time I would like to just increase that variable, which is
supposed to be supported and easy.

Thanks
