Josh,

I'm not really following the details of what you are saying.

You claim "Key-sharing dictionaries were accepted largely without question 
because they didn't harm code that broke them".
Is that true? I don't remember it that way. They were accepted because they 
saved memory and didn't slow things down.

This issue, proposes the same thing: less memory used, no slower or a bit 
faster.

If you are curious about how the first few instances of a class are handled, it 
is described here: 
https://github.com/faster-cpython/ideas/issues/72#issuecomment-920117600

Lazy attribute is not an issue here. How well keys are shared across instances 
depends on the dictionary implementation and was improved by 
https://github.com/python/cpython/pull/28520


It would be helpful if you could give specific examples where you think this 
change would use more memory or be slower.
