Reason being that I favor making code "easier to read" rather than "easier to write".  Adding a new "attribute inheritance" semantic, whether implicitly or explicitly adds cognitive burden to the reader.  You now have to have extra knowledge about when attributes are inherited, whereas with the status quo, you don't have to think about it because all attributes are explicit.  And even if we make it opt in, now you have to learn a new syntax and/or attribute and how it works.  For me the benefit doesn't really justify the added complexity.

I totally agree with Jonathan: it's adding more complexity to the 
language without any specific reason, and D is complex enough 
IMHO.

Python has learned that long time ago: "Explicit is better than 
implicit".

I also don't agree with the rationale:

"is both surprising and burdensome" => opinabile, not for me for 
example, I don't find it surprising at all.
"will be welcome" => idem
