They aren't concerns, just information for those who may find it useful.

And I did consider the possibility that some of these changes are due to backporting from later versions where these changes may have already become standard. I don't have the knowledge to know where to check for what change was made were in what version of what package, so I didn't want to speculate about the reasons.

Thanks for explaining where one of the differences came from. (Edit: And for explaining wmaster0, and what it did. I kinda figured as much as it having 'master' in its title implied, but getting confirmation from someone more informed on the subject is always nice.)

int_ua: What tags are you talking about? The thread tags, or something else?
