Yes, it probably could be separated into 10 patches, but then there is a
chance that I won't do it because sometimes it takes more time for me to
write commit message than to make a code change + extra time to re-check
every patch before sending it out :)

I had the same thought and decided it's not worth the extra effort.

But I'll do it now for complicity, since you're asking about it (in a v2
perhaps).

Thank you very much for the reviews!
