[Development] How to do deprecation

[Friedemann Kleint]

Hi,

 > TL;DR: there's a new [[Deprecation]] wiki page, please review.

It misses an important part, IMO:

Try to get an idea of the impact of your planned deprecation by building 
all of Qt and ideally Qt Creator (producing patches fixing the 
deprecation warnings).

If that turns into an huge exercise taking several days, it becomes 
clear that the deprecation is not feasible.


Regards,

Friedemann
