I agree with your Use Case, and this one of the reasons,
why hourly snapshots have been implemented and had been
default before.

However, as Thorsten stated, we got feedback that the
number of snapshots were overwhelming and confusing, and
thus we decided to not switch it on by default. This
reduces risk, reduces space needed and reduces pain for
people not so much experienced in working with btrfs
and snapper.

Certainly, you are free to change the snapper settings!

What I specifically liked in your statement in addition,
was this: "well defined default cleanup rules". This is
the key part of working with hourly snapshots, and making
use of it in an efficient way; and I think "well defined"
will be different for everybody here in the one or other
way, ...

So long -
