Sorry, I though that were different proyects.

For example, when the root disk is almost full, I'd rather know than get
system/application errors. It has happened to me and I think it is
necessary information.

Because on my computer it shows busy/full for one or two seconds and
I don't have time to remember them, much less to calculate the occupancy
percentage. Humans handle percentages much better than many numbers in a
row (at least I do). Also when running e2fsck it is useful to see
percentages.

This is e2fsck with my patch:

$ sudo e2fsck/e2fsck /dev/sdc5
e2fsck 1.47.0 (5-Feb-2023)
label: clean, 405784/2449408 (16%) files, 6651303/9765625 (68%) blocks
$ 

I think it is helpful to show the percentage. Only number of
files/blocks and totals is not enought.

Sorry I do not understand what you mean. If you want to say that my
sentence "I think that this feature is going to be good for everyone."
is to force the change, I'm sorry. It was just a comment to
explain why I submitted the patch. If it was only useful to me, I would
not have sent it.
