Me too, I really think that we need to rely on a simple rule.

Lets' go on with the discussion. IOW, do we feel a real change is needed ? 
We should avoid an half-baked solution which would please anyone.

IMHO, the order of actions is 'wrong' (sic) enough to be worth to change 
it... with a from __future__ import feature which avoid breaking existing 
code. This implies a correlated warning mechanism which tells a developer 
that he is still using a soon deprecated feature.

A first no brain proposal to begin discussion :

add a tal:importfuture="featurename" statement. (In this case 
tal:importfuture="executionOrder")
- it needs to be declared globally in a ZPT, ie as an attribute of the 
surrounding tag.
- warnings are issued for any page that does not contain the 
tal:importfuture statement but present tags which will be influenced by the 
order of execution change.
- during macro expansion, a warning is issued if an importfuture page uses 
macros from a non-importfuture page
