Dropping legacy support: Moving forward

Following up to this, I would also like the core developers' opinion on Jörg's 
suggestion: would it be feasible to do "show and tell" of Add-ons to the core team to 
discuss ways to handle this (or similar features / workarounds) before they start to 
come up with APIs that no mail Add-on developer needs?

thanks for your consideration,

> I think this question must be answered now, as I do not want to go through this in 5
