That is an opinion and also the consensus as of 15-20 years ago.

It is not the current consensus.

We have used LVM since 2004 or before.  It would take too long
for me to determine the exact start date and the total number
of systems upon which we have deployed LVM.  I can however quote
you from memory the number of problems we have experienced: zero.

For simple systems it is generally easiest to use only a boot and
an "everything else" partition with neither LVM nor complex

For more complex systems LVM is a valuable and robust tool and
much more flexible than partitioning.  Within a single complex
system we may use multiple volume groups with different PE sizes,
different RAID levels, different block/inode ratios, different
reserved block percentages, different mount attributes (e.g.
noexec), and different user quotas.  We currently use ext3
exclusively but others may also use different filesystem types
in different logical volumes as appropriate.

FWIW we have many times found LVM helpful when migrating from
failing hard drives to new drives - just add the new physical
volumes, remove the old physical volumes, and everything is
migrated by magic.
