I also tend to do something like that, but I'm worried that upgrading like
this can broke things badly, especially when upgrading shared libraries, or
some (but not all) packages related to a program. For example, I don't know..
Situation like "yeah, I'll upgrade my terminal because it's harmless", and then
it stops working because I did not upgrade also lib-foo-bar-baz which is used
by my terminal. So let's upgrade lib-foo-bar-baz! but I cannot upgrade it now
because trying to upgrade it wants to remove a ton of other software that I use.
And maybe I cannot install another terminal either because it's GUI software,
which installation triggers all the cascade of removal of other things, etc etc
etc...

You can say "no, something like that cannot happen" but Murphy's law is
always right behind the corner.

Yes, I know the basics of Debian release cycle. I had sid and testing on
this computer before. When the freeze approaches I keep $codename (of the
to-be-released stable distribution) in my sources.list and keep my machine
on stable for some time after the release. But I thought that 2018's spring/summer
was enough time after the release of stretch to try and be on testing again...
