Yes, but the landing page for -03 could have pointers to newer versions (I-D, RFC, Obsoleting RFC, …).

Which you already can do in the source for an I-D.  RFC references are frozen, though.

This could easily be fixed.
I did a PoC for that a while ago.
The data collection for the fixer does need some effort; this could be crowd-sourced or done proactively (probably more expensive than we care about this problem).
