That's true. Anyway, a user should decide whether having the latest
TeX Live is really important. Many users will not spot any difference
even if they use a few years old TeX distribution. It depends on your

If the latest TeX Live is not what you need, you may be satisfied with
updating by apt-get or yum or whatever the Linux distro offers. If you
work mostly with TeX, this may be undesirable. Suppose you work on a
document that must be finished soon and you are not allowed to delay.
Now a security update arrives (maybe a kernel vulnerability is being
fixed). You update your distro in order to get the security fix but
your TeX will be updated too and due to some side effects the document
will no longer compile. This will be a nightmare. If you have TeX Live
from TUG, you can accept the security update without affecting TeX. I
know what i am talking about. Such things happened to me several times
but I always update by tlmgr only when I have enough time to solve
