hm fair enough, but very likely still a mess in the middle run.

What about a compiler daemon library thing that you could write 
small programs for that converts the use of the deprecated 
feature/function into the up to date version.

Think small scale python 2to3 script, but programmable and 
something that actually understands the language.

That way, when you break and api or the language, you provide a 
fix script for each.
Apply them one after the other and you breaking change isn't 
technically breaking anything anymore.

So that way when you update your old program that used D 120.4.7 
to 202.7.2 you rust run the 82 batches of fix up scripts and move 
on with your life.

Did somebody said database migrations ....
