Was there a significant value of breakages for net and stable backports
in past?

Uff, for a second, it did sound like it :)

Well, I think it is good to send a patch to clean something up when you
spot it. If you don't do it, someone else might do it again in the
future anyway.

Plus there is one good reason at least to do this kinds of cleanups.
People tend to copy&paste code without thinking twice. So if you clean
it up here, it might not get copied into other code. That's good.

Random spot&clean is hardly comparable to this.
