Hello, Marco!

I'm sorry, somehow I missed the original letter.

In general the cgroup v1 interface is considered frozen. Are there any particular
reasons why you want to extend the v1 freezer rather than use the v2 version of it?

You don't even need to fully convert to cgroup v2 in order to do it, some v1
controllers can still be used.

Thanks!

Roman
