Well, considering that nobody knows how that "web" ended up there (although it must have been the result of a bug), it's hard to reproduce that part, except by adding it manually...
About preserving unknown components: that behaviour still exists. Actually, if I add a component named "web" to one official Ubuntu source line, software-properties adds it to the other lines too. I wonder if this behaviour should be considered right or wrong...?
