So it would take 2 releases i.e. about 1/2 year?

* In next release autotools build is going to warn that meson should be 
used instead, as autotools support will be eventually removed.

* Next release from that:
   - errors out if specific option isn't used for doing building with 
autotools
   - tells that autotools support will be removed in following release

* Release after that removes autotools support.


(I assume Emil would be the person supporting Autotools during this as 
he had already volunteered for it.)


While I think above is closer to how other large projects do deprecation 
in general (= have clear deprecation period/releases), build system 
changes are probably more often done just with flag day (early in the 
release cycle, as maintaining multiple build systems can be pretty large 
pain).
