As an integrator/developer it annoys me extremely, that the only reason I am not able to override the system extensions Extbase/Fluid is that nobody made a tiny effort to make the caching framework implementations compatible.

Yah, as mentioned, I see the problem and do not doubt it. Actually in my 
extbase teachings, I teach based on master so they get frustrated when 
they can't use that features as well. ;-)

We have a different definition of "few", really. ;-)

For me that sound reasonable but does not put an internal solution over 
an external.

good catch

Yeah, one would think. ;-) From my experience, as soon as you commit 
this to master, people will expect this to fully work on 4.5 LTS. As 
soon as things break, people will complain about "I was told LTS will 
work forever."

So telling them "It is not intended to work with 4.5", they will ask you 
"Why did you make it work, then?". IMHO we take implicit responsibility 
by making it work on 4.5.

Our idea was not having them to keep their own git updated but to 
provide an additional, explicitly marked "unsupported" extension 
(probably even via t3x) for them to fecth from some non-official source.

> I can't imagine anybody could rationally assume otherwise?

But you do imaging that all that people are rationally. ;-)

Of course, just our oppinion and this will be a team descission. So 
let's hear some more people and then decide ...
